Directional Spool Valve H-4WPH10HD4X/O6NET/B10D3 - Bosch Rexroth R901352450

Where a plant already runs compressed air for its controls, a hydraulic valve can be driven from it. This pilot-operated valve works that way and reaches high accuracy of spool position through internal piston position feedback. Up to 160 l/min pass through the 4 ports at up to 350 bar.

Benefits

• Pneumatic actuation, so no electrical control signal is needed in the hydraulic circuit
• Internal piston position feedback, giving an accurate and repeatable spool position
• Flow up to 160 l/min at an operating pressure of up to 350 bar
• Internal pilot oil supply and internal pilot oil return, so no additional lines have to be laid
• Symbol D with 4 ports in 2 switching positions, version without position switch
• Subplate mounting to ISO 4401-05-05-0-05, NBR seals, mass 8.24 kg

Applications

The valve goes into plants whose sequence control is built pneumatically, for instance presses and special machines with separated energy circuits. Internal pilot oil routing keeps the piping on the manifold clear.
