Directional Spool Valve H-4WEH25HC6X/6EG24K4 - Bosch Rexroth R900243916

This pilot-operated directional spool valve reverses the oil flow in a working line without asking the solenoid to move the full flow. A 24 VDC solenoid pilot valve does the switching, while the size 25 main stage releases up to 700 l/min and withstands an operating pressure of 350 bar.

Benefits

• Rated flow of up to 700 l/min through the ISO 4401-08-08-0-05 interface, so a consumer with a large swept volume can be handled by one valve
• Operating pressure up to 350 bar on HL hydraulic fluid with NBR seals
• Two switching positions to symbol C across four ports, giving the control system two clearly defined states
• External pilot oil supply and external pilot oil return keep the pilot pressure independent of the working pressure
• Solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) according to EN 175301-803
• Subplate mounting on a standard subplate allows a swap without touching the piping, at a weight of 16.85 kg

Applications

The valve works in presses, hydraulic power units and test rigs where a large cylinder has to reverse quickly. Size 25 with 700 l/min suits consumers for which a direct operated directional valve no longer offers enough cross section. Subplate mounting lets it drop into an existing control manifold.
