The ZDRE6 VP2 valve is manufactured by Bosch Rexroth and belongs to the ZDRE Proportional Control Valves series. It is a pilot-operated proportional pressure reducing valve that regulates downstream pressure in hydraulic automation circuits. The unit is built in nominal size 6, and its sandwich plate mounting lets it fit between other valve sections without extra piping. The porting pattern follows ISO 4401-03-02-0-05, while port P can withstand up to 315 bar and ports p1, a, and b are limited to 210 bar. The design accommodates a maximum flow of 30 l/min and uses channel P1 for pressure reduction. A pilot flow of 0.65 l/min maintains the internal control loop, matching the performance needed for stable pressure trimming.
Electrical actuation relies on a 24 V DC supply that energizes a solenoid coil with 5 Ω resistance at 20 °C, and the amplifier may deliver up to 1600 mA for full command range. Continuous energizing is possible because the duty cycle is 100 percent. The valve connects through a DIN EN 175301-803 plug and achieves IP65 protection when the mating connector is secured. Total mass is 1.90 kg, so installation on a manifold can be handled by one technician. These electrical and physical characteristics combine with the hydraulic limits introduced earlier to provide dependable pressure modulation in automated machines.
