Hydac Proportional Pressure Relief Valve PDB08P-01 ... moreHydac Proportional Pressure Relief Valve PDB08P-01
Hydac Proportional Pressure Relief Valve PDB08P-01
The PDB08P is a two stage spool type proportional pressure relief valve. If the pressure at port 1 rises above the setting defined by the electrical control signal, the pilot stage opens and allows flow from the back of the main piston to port 2. The resulting pressure imbalance causes the main piston to open against the return spring and allows flow from port 1 to port 2. As a function of the electrical signal the relief pressure at port 1 can be changed steplessly.
Features:
- All surfaces zinc-plated and corrosion proof.
- All valve parts made of high-strength steel with hardened and ground components to ensure minimal wear and to extend service life.
- Rigid design using one-piece body minimizes the effect of eccentricity and maximizes reliability.
- Waterproof design standard.
- Wide variety of connectors available.
- Excellent stability throughout flow range.
- Excellent dynamic performance.
- Low pressure drop by CFD optimized flow-path.
- Screen protected measuring orifice enhances safety.

Hydac Proportional Pressure Relief Valve PDB08PZ
The PDB08PZ is a two stage spool type proportional pressure relief valve. If the pressure at port 1 rises above the setting defined by the electrical control signal, the pilot stage opens and allows flow from the back of the main piston to port 2. The resulting pressure imbalance causes the main piston to open against the return spring and allows flow from port 1 to port 2. As a function of the electrical signal, the relief pressure at port 1 can be smoothly adjusted.
The valve is inversely controlled:
The lowest pressure is created with the highest current. With decreasing control current the pilot-stage closes, the main stage follows the pilot-stage and at port 1 a counter pressure is created, e.g. to accelerate the motor of a fan. The maximum pressure can be pre-set mechanically.Features:
- Preventive against cavitation.
- All surfaces zinc-plated and corrosion-proof.
- Small hysteresis and good stability over the whole pressure and flow range.
- Excellent dynamic performance.
- All valve parts made of high-strength steel with hardened and ground components to ensure minimal wear and extended service life.
- Coil seals protect the solenoid system.
- Rigid design using one-piece body minimizes the effect of eccentricities in cavity and maximizes reliability.
- Low pressure drop by CFD optimized flow-path.
- Adjustable over the entire pressure range.
