I. Overview
The X A/B P-D pneumatic thin film low-temperature single seat regulating valve is a variant of the XTPH dynamic single seat regulating valve and XTPM pneumatic sleeve single seat regulating valve, consisting of a pneumatic thin film multi spring actuator and a low-temperature resistant single seat valve.
Key Features:
1. Up guide or sleeve guide single seat valve, with strong stability.
2. Use a long necked upper valve cover to transport the filling letter away from the low-temperature source, ensuring sealing and safety of personnel operation.
3. The valve seat is fixed with grooves or compressed with a sleeve The structure is simple Easy maintenance and minimal valve seat leakage.
Equipped with pneumatic thin film multi spring actuator The output force is large, and the overall product structure is compact. It is suitable for controlling low-temperature media, but the pressure difference it can withstand is not large.
