The 4WRTE35Q2-1000P-4X/6EG24ETK31/A1M valve belongs to the 4WRTE Directional Control Valves series from Bosch Rexroth and directs oil flow in hydraulic automation circuits. Its size 35 (NG35) body delivers a rated flow of 1000 l/min at a 5 bar differential, while a recommended maximum flow of 3000 l/min supports large-capacity actuators. The main stage tolerates 350 bar on ports p, a, and b, and the pilot stage accepts up to 315 bar supply pressure to shift the spool reliably. Manifold mounting follows the ISO 4401-10-09-0-05 port pattern, and an IP65 enclosure protects internal components from dust and low-pressure water jets. The valve weighs 34 kg, so mounting plates must be sized for this load.
Electrical operation uses a nominal 24 V DC supply, with the coil drawing up to 1.6 A and a maximum power demand of 72 VA. The integrated amplifier responds to a ±10 V command signal on input a1, and its 100 kΩ input resistance minimizes loading on the control electronics. Supply ripple should stay below 2.5 Vpp to avoid unintended spool movement, and a 100 % continuous duty cycle allows round-the-clock service. Wiring terminates in a DIN EN 175201-804 (K31) connector, giving standardized pin assignments and strain relief. These electrical characteristics combine to provide precise, repeatable control of high-pressure hydraulic flow.
