Double Solenoid Operation
Each solenoid shifts the valve spool to its respective operating position.
The valve remains in its last switched position until the opposite solenoid is energised, making it ideal for double-acting cylinders and applications requiring maintained valve position.
The lockable manual override allows simple commissioning, maintenance and functional testing without electrical power.
Mounting Options
Individual body mounted installation
MF520 manifold systems
Suitable for multi-station manifold assemblies. Select the appropriate manifold size from the related products.
