PBM Cryogenic Ball Valves

PBM cryogenic valves have a unique design that provides superior performance through cooling and heating cycles. The valves have been shown to meet leakage criteria per MSS SP-134.

An extended bonnet with an upper set of live loaded stem packings. As metal shrinks, it keeps pressure on seals as temperature goes through cooling and heating cycles. The vented ball allows explosive gas expansion to vent upstream.

Cryogenic valves are optimally oriented with the stem 90° from the horizontal plane. PBM cryogenic valves are capable of operating with the stem oriented as low as 45° above the horizontal plane.

Commissioning the ROTORK CK Range Valve Actuators

The Rotork CK actuator range has been designed to meet the needs of diverse actuation applications required by the valve industry and its customers. The modular design concept enables quick product configuration from stock to customer specification with a very short lead time. 

The CK range provides the customer with a range of options to suit all of their actuation requirements. Rotork CK actuators are designed for minimum user interaction. Their primary goal is to provide safe and reliable actuation in harsh environments. 

The modular CK product range offers simple, robust actuators (CK/CKr) suited to harsh environments with the option for two different control packages (Atronik and Centronik) to meet exact site requirements. Atronik offers modest control and feedback for a simple integrated starter solution. Centronik offers advanced control and feedback for more complex site system integration and increased flexibility through remote mounting.

How to Install a Check-All® Flange Insert Check Valve

The Check-All® Flange Insert (F1, F6, FP) valves are the ultimate check valve in flanged systems. They provide the simplest and most economical way to install check valves in a piping system. The valve body helps position itself while bolts are being installed and tightened.

Check-All® Flange Insert valves are designed to fit between two mating ANSI flanges. Generally speaking, the FIV Class 150 and 300 valves (F1) are designed for standard schedule pipe with Class 150 or 300 flanges, and the FIV Class 600 (F6) valves are designed for schedule 80 pipe with Class 150, 300 or 600 flanges.

Check-All® Insert series valves such as the F1, F6, LP, UV, etc. are designed to use the existing pipe as part of the valve body. This provides a very cost effective solution for valve requirements. As such, part of the valve functions inside the existing pipe; therefore, dimensional clearance must be maintained for proper valve operation.

The Flange Insert valve can also be used as a low pressure relief valve or vacuum breaker by using the desired spring settings.
