Where an axis running at 25 l/min must stay unpressurised at standstill, spool symbol W1 puts both actuator ports on tank. The direct operated size 10 valve works up to 350 bar and takes the command value as ±10 V.

What defines this version is the relieved centre. Spool symbol W1 connects both actuator ports to tank at rest, so the cylinder stands unpressurised and can be moved by hand during set-up. With 25 l/min nominal flow, up to 180 l/min maximum flow and 350 bar, the 4WREE10W1-25 covers smaller axes.

Application
A relieved centre makes sense wherever an axis must stay free to move after shut-down, for instance on clamping fixtures, test set-ups and handling units. At standstill the pump does not deliver against a blocked spool, which lowers oil heating. For load-holding axes the version with symbol E1 is intended.
