Product Overview
The PARKER R5V10-43312A125 (also referenced as 026-65042-0) is a pilot operated pressure relief valve engineered by Parker Hannifin for precise system pressure regulation and overload protection in industrial hydraulic circuits. Utilizing a two-stage pilot operated working principle, the valve maintains stable pressure control across a wide flow range by sensing system pressure at the main poppet and modulating the pilot stage to achieve smooth, accurate relief. This design minimizes pressure override and hysteresis, ensuring reliable protection for pumps, actuators, and downstream components in continuous-duty hydraulic systems.
