Seat Valve electrically force-controlled
Series 2/738-21-23/0804 CRYO
Valve 2/738-21/0804/3802-F-MF AC
2/2-way solenoid valve made from stainless steel for cryogenic media. The sealing element is a metal piston with ring-shaped seat sealing. The piston is guided in the valve cover by piston ring. A pressure differential (delta p) is not required for the operation. These valves are used where it is desired to have the valve function independent of system flow. The valve opens automatically as soon as the pressure downstream of the valve is greater than the pressure upstream of the valve.
