Pilot Operated Relief Valve – POR20-20FP-1K

Pilot Operated Relief Valve POR20-20FP-1K is a pilot-operated hydraulic relief valve with 1-1/4″ female NPT ports designed for high-flow industrial fluid power service; the POR20-20FP model supports up to 100 gpm maximum flow (minimum 4 gpm) and is factory-configured for the 1K adjustable pressure range (350–1000 psi). Key features include pilot operation for stable pressure regulation, compatibility with petroleum-based fluids (ISO VG32–68), recommended 10-micron filtration, cold-start capability up to 250 SUS, maximum fluid temperature to 180°F, and provisions for venting or integral solenoid control (D03 option) for remote or solenoid-operated control of the relief function.

The POR20-20FP-1K delivers dependable overpressure protection and precise pressure control in high-flow hydraulic circuits, making it suitable for industrial and mobile equipment where maintaining a steady setpoint under varying loads is critical. Its pilot-operated design and remote/solenoid venting options simplify integration into automated systems and pilot-control schemes, while the specified filtration, fluid compatibility, and temperature limits help ensure long service life and reliable protection of pumps, actuators, and downstream components in petroleum-based hydraulic systems.
