Low Temp Cryogenic Pneumatic Ball Valve with Actuator
Cryogenic pneumatic ball valve is special ball valve for that medium using its temperature from -40 C to -196 C. Cryogenic ball valve with pneumatic actuator can be used as cryogenic fluids, for example liquefied gas(LNG), liquid nitrogen (LN2), liquid oxygen (LOX), and liquid argon (LAr),etc.The pneumatic cryogenic ball valve is exposed to special cryogenic treatment to guarantee the cryogenic performance from the material. When operating in cryogenic conditions, it won't cause deformation and leakage because of temperature changes.The bonnet of cryogenic pneumatic ball valve adopts a extended design structure, and it is purpose would be to safeguard the part from the packing box, so the packing box is situated far from the cryogenic temperature to guarantee the sealing aftereffect of the packing.

The Features of Cryogenic Pneumatic Ball Valve with pneumatic Actuator:
1. The extended bonnet structure is adopted to help keep the significant temperature from the packing above 0°C, effectively stopping the sealing performance from being decreased because of the working temperature being lacking or perhaps sealing failure.
2. Take cryogenic treatment to avoid cold brittleness of materials and volume change brought on by material phase transition at cryogenic temperature.
3. pneumatic actuator has got the characteristics of huge output torque and small volume. Actuators can be found with optional positioner, travel limit switch box as well as other accessories for automated control.
Optional Accessories When Order the Cryogenic Pneumatic Ball Valve with Pneumatic Actuator:
1.Limit switch box: remote feedback switch signal (explosion-proof type is optional).
2.Solenoid valve: double-acting~3/2-way, single-acting~5/2-way (explosion-proof type is optional).
3.Air set pressure reducing valve: It can regulate the gas source pressure, filtering air.
4.Handwheel mechanism: Turn the handwheel mechanism to open and close the valve manually.
5.Electrical to pneumatic positioner: Input 4~20mA signal to realize valve control function.
