Directional Spool Valve 4WEH16C7X/6EG24N9SK4 - Bosch Rexroth R900975795

Not every movement needs a mid-position. Where a consumer in size 16 only alternates between two oil paths, the pilot-operated directional spool valve 4WEH16C7X/6EG24N9SK4 works with two switching positions to spool symbol C and lets up to 300 l/min pass.

Advantages

• Two switching positions to spool symbol C across four ports, the oil path changes without an intermediate position.
• Flow of up to 300 l/min through the subplate mounting to connection diagram ISO 4401-07-07-0-05.
• Maximum operating pressure of 280 bar with HL hydraulic fluid and NBR seals.
• External pilot oil supply and external pilot oil return, so the pilot stage works independently of the pressure in the main circuit.
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803.
• Weight of 10.4 kg in size 16 as one pilot-operated assembly.

Application

The valve is used where a cylinder or motor is switched between two operating states, for example between rapid traverse and working stroke or when a consumer is cut in and out. The four ports and the subplate mounting to ISO 4401-07-07-0-05 fit common size 16 manifolds. At 300 l/min the switching function stays tied to the external pilot oil supply, which has to be planned separately. Operation is laid out for HL hydraulic fluid with NBR seals.
