Product Overview
The Danfoss PRV2-10-S-0-35 (Part No. 566341) is a precision-engineered proportional pressure relief valve designed for accurate, infinitely variable electro-hydraulic pressure control in industrial hydraulic systems. As a member of the Danfoss PRV2 series, this valve utilizes a proportional solenoid to modulate the pilot pressure acting on a balanced poppet/spool assembly, enabling continuous and repeatable pressure regulation proportional to the input electrical command signal (PWM or current). Unlike fixed-setting relief valves, the PRV2-10-S-0-35 allows dynamic pressure profiling, soft-start/stop ramping, and load-adaptive pressure control, making it a critical component in systems requiring precise force, torque, or pressure management. The “10” size designation indicates a nominal flow capacity of approximately 10 L/min, while the “S” denotes the standard solenoid actuation configuration and the “0-35” range specifies a pressure adjustment span up to 35 bar. This valve is ideally suited for integration into proportional control loops, offering excellent hysteresis characteristics, low pressure overshoot, and high resolution across its full command range.
