Ball valve

pneumaticfor controlfor oxygen

The medium temperature of the cryogenic ball valve is very low, which is used for the control system of cryogenic medium. The valve produced by a special low-temperature process to ensure the low-temperature performance of the material. When it operates in low-temperature conditions, it will not cause leakage due to deformation caused by temperature changes. The valve cover of the cryogenic ball valve uses a long neck structure, which can protect the function of the stuffing box, keep the stuffing box away from the low temperature, and ensure the sealing effect of the packing. Body material - LCB/ 304 Sealing material - PTFE Medium - Liquid oxygen, liquid hydrogen , etc. Options: End connection can be butt-welded, sanitary tri-clamp, threaded, or others upon request. Actuators to reach automatic operation: pneumatic stainless steel actuator (vertical type), pneumatic aluminum actuator (horizontal type), and electric actuator. NC operated: normally closed (fail closed)—air to open, spring to close NO operated: normally open (fail open)—air to close, spring to open AA operated: double-acting—air to open, air to close
