Techniques to Reduce Flashing and Cavitation in Control Valves

Industrial control valves are pivotal in managing fluid flow in numerous applications across various industries, including oil and gas, chemical, and power generation. A common challenge in the operation of these valves is the phenomena of flashing and cavitation, which can severely damage valve components, reduce operational efficiency, and increase maintenance costs. Manufacturers have developed several port modification techniques to mitigate these issues, enhancing the longevity and reliability of control valves. One notable solution in this area is Flowserve Valtek's CavControl technology.

Flashing occurs when the pressure of a liquid drops below its vapor pressure, causing it to vaporize as it flows through the valve, leading to erosion and wear on valve components. Conversely, cavitation happens when vapor bubbles formed from flashing collapse downstream of the valve seat in a liquid phase, causing shock waves that can damage valve parts and connected piping systems. To address these challenges, engineers have devised various port modification techniques focused on controlling the flow within the valve to manage pressure drops more effectively and reduce the likelihood of flashing and cavitation.

One such technique involves the use of multi-stage trim designs. These designs distribute the pressure drop across several more miniature stages or steps within the valve, thereby preventing the pressure at any point from falling below the liquid's vapor pressure. This staged pressure reduction minimizes the energy available for vapor formation as the fluid progresses through the valve, effectively mitigating flashing and reducing the potential for cavitation.

Another port modification approach is incorporating specially designed flow paths that smooth fluid transition from high to low pressure. By carefully shaping these paths, engineers can ensure a more gradual pressure decrease, which helps maintain the liquid state of the fluid and reduces vapor bubble formation. This method not only combats cavitation but also optimizes the flow profile within the valve, enhancing performance and efficiency.

Flowserve Valtek's CavControl technology exemplifies applying advanced port modification techniques to combat cavitation. Cavcontrol utilizes a unique trim design that manages the pressure drop across the valve in a controlled manner, effectively mitigating the conditions that lead to cavitation. The technology incorporates a series of specially engineered notches or grooves in the valve's trim that create a series of pressure-reducing stages. As the fluid passes through these stages, the pressure decreases incrementally, preventing any sudden drop below the vapor pressure and thus avoiding the formation of vapor bubbles.

Furthermore, CavControl's design also focuses on energy dissipation. Controlling the flow path and dissipating the fluid's kinetic energy throughout the valve reduces the fluid's velocity and the impact of any vapor bubbles that may form, minimizing the potential for damage. This approach extends the valve's life and ensures smoother operation and improved control accuracy.

The challenge of flashing and cavitation in industrial control valves requires sophisticated engineering solutions. Port modification techniques, including multi-stage trim designs and controlled flow paths, effectively mitigate these issues. Flowserve Valtek's CavControl technology stands out in this field, demonstrating how advanced design and engineering can enhance the performance and reliability of control valves, ensuring their safe and efficient operation in industrial processes.

Spring-Loaded and Pilot-Operated Safety Valves and Their Industrial Uses

Here's a detailed explanation of spring-loaded and pilot-operated safety valves and their industrial uses.

Spring-Loaded Safety Valves

• Description: These safety valves feature a simple, self-contained design consisting of a valve body, a valve seat, a disc (or poppet), a spring, and an adjustment screw. The spring actively exerts a force on the disc, keeping it pressed against the valve seat and the valve closed under normal operating conditions. You can adjust the spring tension using the adjustment screw, enabling customization of the set pressure of the valve.
• Operation: When the system pressure exceeds the set pressure, the pressure forces the disc away from the valve seat by overpowering the spring force, opening the valve, and allowing excess pressure to vent out. Once the system pressure drops below the set pressure, the spring forces the disc back onto the seat, closing the valve.
• Applications: Industries use spring-loaded safety valves in various applications such as boilers, pressure vessels, and different piping systems, especially where the fluid is gas or steam. These valves respond quickly to sudden increases in pressure.
• Advantages: Spring-loaded safety valves are self-contained, straightforward, and reliable. They operate without the need for any external control or power supply.
• Disadvantages: These valves have limited capacity, might not handle extreme pressure fluctuations effectively, and can suffer from issues like "chattering" (rapid opening and closing), which can damage the valve.

Pilot-Operated Safety Valves

• Description: Pilot-operated safety valves are more intricate than spring-loaded valves. They comprise two main components: a main valve and a pilot valve. System pressure and a smaller spring close the main valve, acting on a larger surface area. The pilot valve, essentially a small spring-loaded safety valve, controls the opening and closing of the main valve.
• Operation: When system pressure surpasses the set pressure, the pilot valve opens first, reducing the pressure on top of the main valve. This action opens the main valve, venting the excess pressure. As the system pressure drops below the set pressure, the pilot valve closes, and the main valve reseals.
• Applications: Industries commonly use these valves in high-capacity and high-pressure applications such as chemical processing plants, power plants, and oil and gas facilities. They are ideal for liquid-based applications because they can handle large pressure fluctuations and higher flow capacity.
• Advantages: Pilot-operated safety valves offer greater capacity, improved performance with liquids, and increased stability compared to spring-loaded valves. They can accommodate more significant pressure fluctuations and are less susceptible to chattering.
• Disadvantages: These valves are more complex and costly compared to spring-loaded valves. They might also need periodic maintenance to ensure proper functioning.

Both types of safety valves play a crucial role in maintaining safe operating conditions in industrial systems. They prevent equipment damage and protect workers from potentially dangerous situations. The choice between spring-loaded and pilot-operated safety valves depends on the application's specific needs, such as the fluid type, operating pressure, and flow capacity.

What are API 526 Safety Valves?

API 526 is a standard published by the American Petroleum Institute (API) that covers safety valves for use in the petroleum and natural gas industries. API 526 safety valves are designed to protect against overpressure conditions in piping systems, vessels, and equipment by automatically relieving excess pressure. They are used to protect against hazards such as explosions, structural damage, and injury to personnel. API 526 covers the design, materials, testing, and installation requirements for safety valves in these applications.

API 526 is a purchasing specification for "API safety valves" that specifies nominal diameters, flange pressure ratings, center-to-face dimensions, flow areas, body and spring materials, and service restrictions. API safety valves are utilized in the petrochemical sector globally, both on and off-shore. Standardized plants, blow-down systems, and large pipework sections distinguish these applications. The LESER type 526 combines the API standards and the ASME Code requirements with the LESER range's established and tested service reliability.

Control Valve Application Notes

Using an incorrectly applied or sized control valve may have significant ramifications for operation, productivity, and, most importantly, safety. Here is a brief list of fundamentals to consider: 

Control valves are not isolation valves: 

Control valves do not isolate a process and do not offer a bubble-tight seal, and utilization in a shutoff capacity is unwise. 

Choose the suitable materials for the job: 

The valve body, seat, and wetted materials must all be compatible with the process under control. Before selecting a valve, evaluate the pressure ratings, operating temperatures, and material compatibility. 

Sensor placement: 

Place the flow sensor upstream of the control valve when configuring the control loop. When the flow sensor placement is downstream of the control valve, exposure to an unstable fluid (bubbles) created by the flashing and turbulence of the flow in the valve cavity is possible.

Control precision and mechanical constraints: 

Consider the degree of controllability you need and the inherent Deadband produced by your valve and associated components. Deadband is the built-in movement that occurs in a control valve between the signal change and the direction of the valve, which exacerbates by worn or poorly designed couplings between valve and actuator, mechanical sensor tolerances, friction in the valve stems and seats, or an undersized actuator. Due to opening/closing oscillations, too much deadband leads to poor controllability (hunting). 

Stiction: 

Stiction is the "stickiness" in valve action induced by packing gland, seat, or force against the disk friction. It may happen if the valve sticks in one position for a prolonged time or is constantly traveling in a minimal range for an extended period. The actuator must apply more force to break the disk free, resulting in overshoot and poor control. 

Tuning the loop controller and/or positioner: 

A poorly configured loop controller or positioner is often the source of poor control and loop instability. Advanced auto-tuning capabilities in PI (proportional with integral), PD (proportional with derivative), and PID (proportional with integral and derivative) controllers have replaced human (often trial and error) loop tuning. 

Valve sizing should be correct: 

Control valves are often oversized, permitting maximum flow at just a tiny percentage of total travel. Minor adjustments in valve position have a significant impact on flow. A high valve-position-to-flow ratio promotes continual "hunting," which leads to excessive valve wear. A decent rule of thumb is to size a control valve at around 70% to 90% of its travel. 

What sort of flow characteristics does your valve produce: 

The flow characteristic of a control valve is the connection between the position of the valve disk, gate, or globe and the change in flow rate through the valve under normal circumstances. A linear flow characteristic is desirable. However, different valve designs have varying flow characteristics, some of which are linear and others that are not. Globe control valves have linear flow properties, while butterfly and gate valves have non-linear flow characteristics. Manufacturers will often create specifically shaped disks or orifices to "characterize" the valve's flow to improve linearity.

The above is a brief list of the most common things to consider when applying control valves. There are many other criteria to consider. It is suggested in the strongest terms to consult with an experienced application expert before selecting or using a control valve.

Linear and Quarter-turn Industrial Valves

Various valves are designed and used for multiple roles in process control. Linear and quarter-turn valves are two types of valves used to regulate and control fluid flow in the industry. Their design and construction reflect the intended use of the valves, with each suited to a different class of service. 

All valves work by controlling the position of an internal structure that obstructs fluid passage to some extent. In general, fluid flow at the valve classifies as unrestricted (valve fully open), stopped (valve fully closed), or throttled (valve partially open). The operational requirements of the process will determine whether only two of those conditions (fully open and fully closed) or all three are required. When choosing an appropriate valve, the fluid, the process, and the surrounding environment must be considered. It is not always a simple task. 

Linear valves distinguish themselves using straight-line motion to position the valve plug, disc, diaphragm, or other flow controlling elements. The linear valve trim's shape, size, and arrangement provide the operator with a flow range through the valve. The linear valve's positioning allows it to regulate fluid flow slower but more accurately. Linear motion valves include gate and fixed cone valves—linear valves best suit flow control.

Quarter turn valves move from fully open to closed by rotating a shaft connected to the controlling element 90 degrees. Their relatively simple operation allows for a rugged and compact design. The ability of quarter-turn valves to quickly reposition from open to closed positions is one of their distinguishing features. The torque required to operate the valves is typically low to moderate. Quarter turn valves include ball and butterfly valves. 

Depending on the situation, linear valves and quarter-turn valves are the best choices for specific process environments. The linear valve's accuracy and ability to move in a linear fashion rather than a quarter-turn come with easy maintenance and a lower likelihood of cavitation. Both valve types are widely used and are not competing for the same application. Each excels in a specific set of applications.

Valve Positioners

Valve positioners perform the function of determining the error between the optimum vale position and actual valve position and provide a corrective output. Specialized sensors on the valve stem or shaft correspond to the setpoint from the control system. The positioner's output is sent electrically or pneumatically to a valve actuator, which moves the valve in the corrective direction. 

As a control valve accessory and the interface between the control system and valves, positioners play a vital role in ensuring the process loop's performance. The valve positioner adjusts the valves' opening, thereby varying the valve's flow rates, from completely shut or wide open to anywhere in between.
