Product Overview
The DENISON ZRE-AB-01-D1 (Part Number: 098-91020-0) is a high-performance proportional pressure relief valve engineered by Parker Denison for precise electro-hydraulic pressure control in demanding industrial systems. This valve operates on a proportional solenoid actuation principle, where an electrical command signal proportionally modulates the pilot pressure stage, thereby delivering infinitely variable pressure regulation across the full operating range. Unlike fixed-setting relief valves, the ZRE series enables dynamic, real-time pressure adjustment through analog or PWM control signals, making it an essential component in closed-loop hydraulic circuits requiring accurate force, torque, or pressure profiling. The valve is designed as a direct-operated, poppet-type pilot stage with a balanced main spool, ensuring minimal hysteresis, excellent repeatability, and fast response to command signal changes. Its robust construction and precision-machined spool-to-body clearances allow it to function reliably as both a pressure-limiting safeguard and an active pressure-control element in proportional hydraulic systems.
