PDB08P-01
Pressure Relief, Pilot Operated, Spool Type
16 gpm (60 l/min) • 5000 psi (350 bar)
Description
A screw-in cartridge, pilot operated, spool type, pressure relief valve, intended for use as a pressure limiting device. This valve can be infinitely adjusted across a specified range using a variable electric input. Pressure output is proportional to DC current input.
Operation
The PDB08P-01 blocks flow from port 1 to port 2 until sufficient pressure is reached at port 1 to open the pilot stage by offsetting the electrically induced solenoid force. The pilot stage opens and allows flow from the back of the main piston to port 2. The resulting pressure imbalance causes the main spool to move against the return spring and allows flow from port 1 to port 2.
Electrical current increase will increase the relief pressure setting. With no current applied to the solenoid, the valve will relieve at approximately 75 psi.

PDB12P-01
Pressure Relief, Pilot Operated, Spool Type
53 gpm (200 l/min) • 5000 psi (350 bar)
Description
A screw-in cartridge, pilot operated, spool type, pressure relief valve, intended for use as a pressure limiting device. This valve can be infinitely adjusted across a specified range using a variable electric input. Pressure output is proportional to DC current input.
Operation
The PDB12P-01 blocks flow from port 1 to port 2 until sufficient pressure is reached at port 1 to open the pilot stage by offsetting the electrically induced solenoid force. The pilot stage opens and allows flow from the back of the main piston to port 2. The resulting pressure imbalance causes the main spool to move against the return spring and allows flow from port 1 to port 2.
Electrical current increase will increase the relief pressure setting. With no current applied to the solenoid, the valve will relieve at approximately 25 psi.

PDB16P-01
Pressure Relief, Pilot Operated, Spool Type
79 gpm (300 l/min) • 5000 psi (350 bar)
Description
A screw-in cartridge, pilot operated, spool type, pressure relief valve, intended for use as a pressure limiting device. This valve can be infinitely adjusted across a specified range using a variable electric input. Pressure output is proportional to DC current input.
Operation
The PDB16P-01 blocks flow from port 1 to port 2 until sufficient pressure is reached at port 1 to open the pilot stage by offsetting the electrically induced solenoid force. The pilot stage opens and allows flow from the back of the main piston to port 2. The resulting pressure imbalance causes the main spool to move against the return spring and allows flow from port 1 to port 2.
Electrical current increase will increase the relief pressure setting. With no current applied to the solenoid, the valve will relieve at approximately 90 psi.

PDR08-01 Pressure Reducing/Relieving Direct Acting, Spool Type 3 gpm (12 l/min) • 5000 psi (350 bar) Description A screw-in cartridge, direct acting, spool type, pressure reducing/relieving valve, intended for use as a pressure control device, which can proportionally control the reduced pressure across the specified range using variable electrical input signal. Reduced pressure output is proportional to DC current input. This valve maintains a constant reduced pressure regardless of pressure variations in the primary system. In addition to the reducing function, this valve also provides a relief function from the reduced pressure port to the tank port if pressure in the secondary circuit exceeds the set pressure. Operation When de-energized the PDR08-01 allows flow from port 1 (reduced pressure port) to port 3 (tank). Port 2 (inlet) is blocked. When current signal is applied, the solenoid armature moves the control spool and sets the control (reduced) pressure at port 1. Increasing the current applied will increase the reduced pressure proportionally. Port 3 is vented to tank. Back pressure on port 3 is directly additive to the pressure setting.

PDR08P-01
Pressure Reducing/Relieving Pilot Operated, Spool Type

Reduced pressure output is proportional to DC current input. This valve maintains a constant reduced pressure regardless of pressure variations in the primary system. In addition to the reducing function, this valve also provides a relief function from the reduced pressure port to the tank port, if pressure in the secondary circuit exceeds the set pressure.
Operation
The PDR08P-01 allows flow from port 2 to port 1 until sufficient pressure is reached at port 1 to open the pilot section by offsetting the electrically induced solenoid force. Increasing electrical current will increase the control (reduced) pressure at port 1. Any pressure on port 3 is additive to the pressure setting. With no current applied to the solenoid, the valve will maintain pressure at approximately 75 psi, regardless of the pressure at port 2.
