DESCRIPTION APPLICATION
Pilot or direct operated proportional pressure relief valve in flange The electrical remote control in conjunction with process controls
or sandwich construction. When the operating pressure adjusted allows economical solutions with repeatable processes. Miniature
by means of the proportional solenoid is reached, the valve opens values are used where both, reduced dimensions and weight are

and connects the protected line with the drain to the tank. These important.
proportional valves are very sensitively adjustable. For flange or
sandwich executions with pressure relief in port P, there is a mano-
meter connection. For the control, Wandfluh proportional ampli-
fiers are available (see register 1.13).
