Directional Spool Valve Z4WEH 22 E63-5X/6EG24NTK4 - Bosch Rexroth R978896905

During commissioning and fault finding it matters whether the valve can be shifted by hand. The Z4WEH 22 E63-5X/6EG24NTK4 has a manual override, takes pilot oil externally and carries up to 650 l/min at 315 bar.

Benefits

• Manual override for commissioning and fault finding without electrical control.
• External pilot supply, internal pilot drain, one feed line in the manifold is enough.
• 650 l/min at 315 bar in size 25, ISO 4401-08-08-0-05 pattern.
• Spool symbol E63, 2 switching positions, sandwich plate connection.
• 21.1 kg, NBR seals, 24 VDC through a 3-pole (2 + PE) plug to EN 175301-803.

Technical data

Applications

The valve is fitted in manifolds of presses, test rigs and special machinery where the axis has to move even without control voltage. External pilot supply allows a dedicated pilot feed, while the internal drain keeps the piping short. As a sandwich plate it slots into an existing valve stack.
