Product Overview
The HAWE PMVP 4-41/G 24 is a precision proportional pressure relief valve engineered by HAWE Hydraulik for continuous, electro-proportional control of system pressure in industrial hydraulic circuits. Unlike a conventional pilot-operated relief valve, the PMVP series uses a proportional solenoid to infinitely vary the pressure setting in direct proportion to the electrical command signal, enabling smooth pressure ramping, load-holding, and closed-loop pressure regulation. The valve is a direct-acting, seat-and-spool design in which the solenoid force is balanced against the hydraulic force on the valve poppet, so that output pressure tracks the input current with high repeatability. The “4-41” size designation corresponds to the NG 4 (DIN 24340 / CETOP 3-style) interface, and the “G 24” suffix denotes a 24 V DC proportional solenoid coil. This valve is typically used as a pilot or main pressure control element in injection molding machines, hydraulic presses, and test stands where precise, electrically modulated pressure control is required.

Engineering Features & Advantages
- Precision Proportional Performance: The proportional solenoid provides a pressure setting that varies continuously and linearly with the command current, allowing stepless pressure adjustment rather than fixed stepped settings. This enables accurate pressure ramping and smooth load control in closed-loop systems.
- Direct-Acting Response: Because the valve is direct-acting, it responds quickly to changes in command signal and to pressure transients, giving fast, stable pressure regulation with minimal hysteresis and good repeatability.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction and wear-resistant internal components for extended service life.
- Direct Fit Replacement: Precision-manufactured to original HAWE specifications for direct replacement, minimising downtime and eliminating fitment issues.
Typical Industrial Applications
This valve is typically used as a pilot or main pressure control element in injection molding machines, hydraulic presses, and test stands where precise, electrically modulated pressure control is required.
