Solenoid On/Off Valves for Cryogenic Liquids
Built to withstand the extreme cold of liquid nitrogen and liquid oxygen, these valves are cleaned and bagged for high-purity applications. They operate on electricity to automatically start and stop flow.
All valves are normally closed unless actuated. The actuator is directly mounted to the valve body to minimize movement and reduce wear.
304 stainless steel valves are more corrosion resistant than brass and bronze valves.
Zero pressure drop valves don’t require a minimum pressure drop between the inlet and outlet for operation. Pressure drop assisted valves require a minimum pressure drop between the inlet and the outlet for operation; the upstream pressure must be greater than the downstream pressure.
NEMA 2 valves resist light splashing water and dust, and their enclosures are rated IP50 for additional protection from dust. Valves rated NEMA 4 and IP65 resist dust, splashing water, and washdowns.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
