Proportional Pressure Relief Valve series DVPSB−3B

Pressure [bar]


Flow rate [L/min]


Proportional pressure relief cartridge valves Series DVPSB−3B… are two stage, spool type valves. They limit the inlet pressure in port 1 to a value that is proportional to the solenoid current. All external parts are chromited (Cr VI− free) and are thus suitable for use in the harshest operating environments. The core tube / slip−on coil design allows coils to be changed without opening the hydraulic envelope, even when the valve is under pressure. Coils can be secured at any angle thro’ 360° and can be supplied with the most common electrical connectors (see ordering code). For customers who manufacture their own manifold blocks, we offer form−tool sets for sale or hire. Use the GEBAA body with threaded ports (G1″) for line−mounting applications.
