HydraForce PR10-36A — Pilot-Operated Pressure Reducing/Relieving Valve

The PR10-36A is a screw-in, cartridge-style, pilot-operated spool valve designed to regulate pressure in secondary hydraulic circuits—not a standalone relief valve. In steady state, it allows bidirectional flow from port ② to port ①, with the spring chamber drained at port ③. When pressure at port ① reaches the set value, the spool shifts to restrict inlet flow from port ②, thereby regulating pressure at port ①. In this mode, the valve simultaneously relieves excess pressure from port ① to port ③ .

Key Distinction from Relief Valves

Unlike a pilot-operated relief valve (e.g., HydraForce RV series), which primarily limits system pressure by dumping flow to tank, the PR10-36A actively regulates downstream pressure while also providing relieving capability. This makes it suitable for secondary circuit pressure control, not for primary system overpressure protection alone.

Ordering Notes

The base model PR10-36A-0 requires a spring range suffix (e.g., -15 for 150–1500 psi, -30 for 400–3000 psi) and seal/option codes.
Confirm whether you need the cartridge only or a ported body assembly.
Aftermarket versions exist (China-origin); verify whether genuine HydraForce is required for your application.
