Pressure valve has control piston with converter to change position information into electrical signal for output pressure

摘要

The pressure valve has a control piston and an electromechanical converter (28) to convert the position of the actuator (23,24) into an electrical output position signal (ux), which forms a datum for the position of the actuator and for the metering value of the output pressure. The pressure valve can be a pressure reduction valve (10) or pressure limiting valve. Claims include a pressure monitor for the pressure valve.
