Seat Valve electrically force-controlled
Series 37-08
Valve B3705/0804/4278-3G-F1-OF DC
2/2-way solenoid valve type 37 for gases and solids-free liquids, has a force pilot operated type of control and switches at a pressure difference from 0 bar to 40. The force pilot operated type of control can be used in all those fields where directly acting valves are required. The sealing element is a metal piston with ring-shaped seat sealing. The piston is guided in the valve cover by piston ring. This is a robust valve type, suitable for high pressures, and thanks to the use of PTFE sealing materials it is also suitable for a wide range of applications.
