Product Overview
The HYDRAFORCE PR50-38A-0-P-33 is a direct-acting, cartridge-style pressure relief valve engineered for precise hydraulic system overpressure protection. Manufactured by HydraForce, a globally recognized leader in high-performance hydraulic cartridge valves, this model belongs to the PR50 series — a proven platform designed for reliable pressure control in demanding industrial circuits. The valve operates on a direct-acting poppet or spool principle, where system pressure acts directly against a spring-loaded sensing element. When the preset cracking pressure is reached, the valve opens to divert excess flow to tank, thereby safeguarding downstream components such as pumps, cylinders, motors, and seals from pressure spikes and sustained overpressure. With its compact cartridge footprint and robust construction, the PR50-38A-0-P-33 integrates seamlessly into manifold blocks and custom hydraulic integrated circuits (HICs), delivering consistent, repeatable pressure regulation across a wide range of operating conditions.
