Low temperature stainless steel as the design of the pneumatic valve standards

low temperature stainless steel by the pneumatic valve design standards, according to the conditions of use, low temperature stainless steel as the design of the pneumatic valve has the following requirements:
and pneumatic valves in medium at low temperature and ambient temperature should have the ability to work long hours.
and pneumatic valves should not be a low temperature system of a significant source of heat. This is because the heat flow in addition to the lower thermal efficiency, such as flow too much, still can make internal fluid evaporation rapidly, produce abnormal booster, dangerous.
and low temperature medium should not produce harmful to the hand wheel operation and packing seal performance.
and direct contact with the low temperature medium pneumatic valve assembly should have explosion and fire prevention structure.
, work under low temperature of the pneumatic valve assembly does not lubrication, so you need to take structure measures, in order to prevent the friction abrasion.
