Directional Spool Valve Z4WH16E63-5X/QMABG24 - Bosch Rexroth R901390501

A shut-off valve does not need its own station in the manifold, it can sit as a sandwich plate underneath the existing valve. That is how the hydraulically actuated Z4WH16E63-5X/QMABG24 works, at a flow of up to 300 l/min and a maximum operating pressure of 315 bar.

Benefits

• Sandwich plate design, no separate station needed on the mounting face of the manifold.
• Hydraulic actuation, so neither an electrical connection nor a control voltage is required.
• Maximum operating pressure 315 bar at a flow of up to 300 l/min.
• Two switching positions to symbol E63 across four ports, without manual override.
• Size 16 to port pattern ISO 4401-07-07-0-05, 15.06 kg, NBR seals for HL hydraulic fluid.

Applications

In circuits where a cylinder has to be shut off hydraulically in a given position, the sandwich plate saves a second valve station and the drillings leading to it. Hydraulic actuation takes its signal from the circuit itself, so the function survives a loss of electrical supply. Leaving out a manual override prevents the shut-off function from being released unintentionally on site.
