Pilot Operated Relief Valve – POR20-12FS-3K

Pilot Operated Relief Valve POR20-12FS-3K is a 3/4″ POR20-series pilot-operated relief valve with #12 female SAE (T‑style) ports, adjustable 1000–3500 psi (3K) range, and a compact design engineered for low pressure differential control. The valve supports up to 50 gpm maximum (2 gpm minimum), accepts ISO VG32–68 petroleum-based fluids, recommends 10‑micron filtration, and handles temperatures to 180°F (82°C) with cold‑start viscosity limits specified; it can be vented for remote control and accepts optional solenoid control for integration into automated circuits.”

Designed for stable pressure regulation and continuous-duty hydraulic systems, the POR20-12FS-3K provides precise overpressure protection, reduced pilot-induced chatter, and improved system efficiency compared with direct‑acting alternatives. Typical applications include industrial power units, mobile hydraulics, valve banks and machinery where tight pressure control, high flow capacity and remote or solenoid control options are required; the robust specification and recommended filtration make it well suited for demanding service environments and integration into OEM hydraulic circuits.”
