Directional Spool Valve 4WEH16H7X/6EG24N9TK4 - Bosch Rexroth R900933953

The 4WEH16H7X/6EG24N9TK4 distributes the oil flow over three switching positions and returns the pilot oil internally to tank while it is supplied externally. At a maximum flow of 300 l/min and a maximum operating pressure of 280 bar the valve weighs 9.71 kg.

Advantages

• Three switching positions with spool symbol H, that is two working positions plus a defined centre position.
• Internal pilot oil return with external pilot oil supply saves a dedicated return line in the manifold.
• Flow of up to 300 l/min at a maximum operating pressure of 280 bar.
• Subplate mounting according to ISO 4401-07-07-0-05 with 4 ports.
• Solenoid actuation on 24 VDC, connected by a 3-pole connector (2 + PE) according to EN 175301-803.
• Weight of 9.71 kg, NBR seals for hydraulic fluid HL.

Application

Valves like this sit in the manifolds of presses, lifting gear and test rigs where several actuators are fed from one common pilot circuit. The internal return shortens the piping because the pilot oil drains through the tank port of the valve. With 24 V direct voltage the solenoid can be switched straight from the machine control.
