Seat Valve electrically force-controlled
Series 2/738-23-24-25-27/0804 CRYO
Valve 2/738-25/0804/.272-F-5P AC, DC
Our classic in the field of cryogenic applications. If you are looking for an absolutely safe valve for shutting off cryogenic fluids down to -196°C, then you have come to the right place. Type 2/738 is a cryogenic valve adapted to the application with high functional safety. The valve opens automatically as soon as the pressure downstream of the valve is greater than the pressure upstream of the valve.
