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.
