The DR30G6-5X/200YM valve is manufactured by Bosch Rexroth and belongs to the DR Pressure Reducing Valves series. It limits downstream pressure in hydraulic automation circuits. The nominal size is 32, which defines the passage area for high-flow lines. A threaded connection allows direct pipe mounting, and the main port thread of G1 1/2 fits common large-bore fittings. Set pressure can be tuned up to 200 bar, and a lockable rotary knob with scale lets technicians adjust and secure this value while reading it directly.
The valve tolerates a maximum operating pressure of 350 bar, allowing safe use on high-pressure supplies while lowering pressure on the controlled outlet. Pilot oil is taken internally, while an external return keeps pilot flow separate from the main circuit. Counter pressure at port Y can reach 350 bar without upsetting regulation accuracy, and a peak threaded flow of 400 l/min supports high-throughput systems. The unit may be installed in any position, is not equipped with a check valve so reverse flow must be handled externally, and requires fluid cleanliness to ISO 4406 20/18/15.
