Proportional pressure relief valves, PDB-6I
Proportional pressure relief valves from the PDB-6I series are direct-acting, pressure-stable valves, suitable for pressures of up to 700 bar and flow rates of up to 25 l/min. In addition to a compact and lightweight design, they offer outstanding leaktightness and a linear pressure-flow curve.
- Max. operating pressure: 1000 bar
- Max. flow rate: 25 l/min
- Size: Size 6 to Bieri standard
Features
Direct operated or pilot operated, seat tight, linear pressure-flow characteristic, as "standalone" valve or in valve linkage with sub-bases (AP700 and RP700)
Benefits
Seat-tight function with standardised NG6 connection surface to DIN 24340 / ISO 4401 / CETOP RP 121 H, any orientation of the solenoid plug and no need to open the pressure-tight chamber when changing coils, stable control behaviour, easily replaceable main stage orifices, good suitability for mineral oil
Industries & Applications
For electrical control of the supply or working pressure in an open or closed control circuit.
Mounting
Seat design, with manual override, 360° rotatable and replaceable solenoid coil, mounting on individual sub-bases as "standalone" valve or in valve linkage with sub-bases (see technical data sheets AP700 and RP700), direct force transmission to the valve needle, manual override for manual function test, with guided closing element. The pilot operated valve consists of the direct operated valve, main stage and end plate.
