Directional Spool Valve 4WEH 16 HD7X/OF6EG24N9TDK25L - Bosch Rexroth R978908155

Machines built to North American practice do not carry an EN connector on the valve but an ANSI one. The directional spool valve 4WEH 16 HD7X/OF6EG24N9TDK25L uses a 5-pole connector according to ANSI/B93.55M-1981 and switches up to 300 l/min at a maximum of 280 bar.

Benefits

• 5-pole electrical connector to ANSI/B93.55M-1981, matching wiring built to North American standards.
• External pilot oil supply, internal pilot oil return, pilot oil comes from its own circuit and drains internally to tank.
• 300 l/min at size 16, maximum operating pressure 280 bar.
• Two switching positions to symbol D across four ports, mounting pattern ISO 4401-07-07-0-05.
• Solenoid actuation at 24 VDC, NBR seals for HL hydraulic fluid.
• 8.9 kg for the pilot-operated unit.

Applications

This version targets machinery built to North American wiring practice or shipped to that market. Hydraulically it matches the other size 16 valves with subplate mounting, so manifold and piping can stay as they are. The mixed pilot oil routing suits circuits whose P line is unloaded at times while the tank line stays calm.
