Proportional pressure relief valves, PDB-6B
Proportional pressure relief valves from the PDB-6B series are direct-acting and leaktight valves, for electrical control of the supply or working pressure in open-loop or closed-loop control system.
- Max. operating pressure: 1000 bar
- Max. flow rate: 5 l/min
- Nom. size: NG 6 in acc. with Bieri standard
Features
Direct-acting or pilot-operated, leaktight, linear pressure-current curve, as stand-alone valve or in valve stack with connection plates (AP700 and RP700)
Benefits
Leaktight function with Bieri mounting faces, any orientation of solenoid connector and no opening of pressure-sealed chamber required for coil change, stable control behaviour, well suited to mineral oil
Industries & Applications
For electrical control of the supply or working pressure in an open or closed control circuit.
Mounting
Poppet design, with manual override, 360° rotating and changeable solenoid, can be mounted on single connection plates as stand-alone valve or in valve stack with connection plates (see technical data sheets AP700 and RP700), direct force transmission to valve needle, manual override for manual function test, with guided closing element. The pilot-operated valve is made up of a direct-acting valve, main stage and end plate.
