Pilot Operated Relief Valve – POR20-12FS-1K

The POR20-12FS-1K Pilot Operated Relief Valve is a POR20-series, pilot-operated hydraulic relief valve in a 3/4″ (#12) female SAE port configuration designed for stable, high-capacity pressure regulation. Key features include a pilot-actuated main stage for low pressure differential and smooth modulation, an adjustable pressure range (standard 1,000–3,500 psi), maximum flow capacity up to 50 gpm with a minimum flow around 2.0 gpm, and available female SAE/NPT port options per POR20 series specifications. Recommended system practices include 10-micron filtration and a maximum operating temperature near 180 °F to ensure longevity and reliable performance.

As a pilot-operated design, the POR20-12FS-1K delivers precise, stable overpressure protection and higher flow capacity with less tendency to chatter than direct-acting relief valves—benefits that improve system control, component life, and safety in mobile and industrial hydraulic applications. Typical uses include pressure regulation and overpressure protection in hydraulic circuits for mobile equipment, implements, winches, pumps and other high-flow systems where smooth modulation and high-capacity relief are required.
