Stainless steel low temperature by the pneumatic valve pictures of extension rod

Stainless steel low temperature of extension rod by the pneumatic valve is suitable for medium temperature in - 40℃～ - 196 ℃ of pneumatic valves, general medium for ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products such as low temperature medium without particles, used as on-off or adjust, can also be used to other management systems of low temperature and cryogenic medium. Low temperature as the main parts of pneumatic valve is treated with low temperature, and low temperature impact test for every batch of sampling, to ensure that the pneumatic valve in the condition of low temperature embrittlement, withstand low temperature medium. To ensure material low temperature performance, to ensure that finishing size, in order to prevent the pneumatic valve in the condition of low temperature and deformation caused by temperature change caused by the leakage. Pneumatic valve size: 15-1200 - mm ( 1/2 ~ 48“; ） 。 Link form: flange, welding, thread. Pneumatic valve material: LCB, LC3, CF8. Working temperature: - 46℃、- 101℃、 - 196℃、- Applicable medium: liquefied natural gas (LNG), ethylene, propylene, etc. Drive mode: manual, pneumatic, electric.



low temperature by the pneumatic valve principle of extension rod:



application under low temperature conditions by the pneumatic valve, medium temperature is very low, if the ordinary pneumatic valves, the low temperature will make the inside of the pneumatic valve stuffing box packing frozen, can't play a role of sealing. So, a pneumatic valve need to cover is extended from the pneumatic valve seal to the length of the stuffing box at the bottom of the tower, with full isolation and cooling distance, pneumatic valve body of low temperature medium is not the stuffing freeze to death.
