Directional Spool Valve Z4WEH10E63-4X/6EG24N9ETK4/B10D3 - Bosch Rexroth R900943933

As a sandwich plate the valve sits directly under the directional valve, needing no level of its own in the control block, which saves height and piping. The spool with symbol E63 works in two switching positions and the hole pattern follows ISO 4401-05-04-0-05. It passes up to 160 l/min at a maximum of 315 bar and carries a concealed auxiliary actuation.

Benefits

• Sandwich plate to ISO 4401-05-04-0-05, no separate level in the control block
• Spool symbol E63 in two switching positions on four ports
• Flow up to 160 l/min, maximum operating pressure 315 bar
• Pilot-operated, with concealed auxiliary actuation for emergency operation
• 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803
• Mass 4.9 kg in size 10, NBR seals for HL fluid

Application

The design is chosen when an existing valve stack has to gain a shut-off function without machining a new block. Concealed auxiliary actuation lets an operator move the load by hand during a power failure. On commissioning that is often the deciding point.
