Directional Spool Valve 4WEH16HZ7X/OF6EG24N9S2K4/P4,5 - Bosch Rexroth R900706127

With spool symbol Z this valve works in two switching positions and has no mid position. Pilot oil supply and pilot oil return both sit outside, keeping the pilot stage decoupled from the main circuit. Flow reaches 300 l/min and mass comes to 10.82 kg.

Benefits

• Spool symbol Z in two switching positions on four ports
• External pilot oil supply and external pilot oil return
• Flow up to 300 l/min at a maximum of 280 bar
• Size 16, subplate mounting to ISO 4401-07-07-0-05
• Solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803
• Mass 10.82 kg, NBR seals for HL hydraulic fluid

Application

The build goes where a load is reversed between two defined states while the main circuit idles without pressure at times. Pilot pressure then arrives from a source of its own through port X. Pilot oil return runs separately through port Y.

Manufacturer

Bosch Rexroth lists this pilot-operated directional valve 4WEH16HZ7X/OF6EG24N9S2K4/P4,5 under material number R900706127. Data sheets RE 24751 and RE 07600-B carry the characteristic curves, the installation dimensions and the interface data. Without external pilot pressure the spool stays in its initial position.
