The solenoid valve type 1/041 with threaded connection, is forced control type. The sealing element is a metal piston with a ring-shaped PTFE seat seal. The valve type is robust and suitable for high pressures up to 70 or 100 bar. In valves with forced control, the servo principle is coupled with direct actuation. Forced control valves combine the advantages of these types of control. The valves switch from 0 bar up to the maximum operating pressure and can be used where direct-acting valves are used.
