Designed for single acting cylinders which are supposed to hold pressure.
Ensures smooth decompression prior to return of the cylinder ram.
Large return oil passage to reduce pressure drops, allowing rams to return under low external forces.
Valves with Quick Exhaust feature has larger return passages. They are meant for rams having either very low retractive forces or must return rapidly under normal forces.
Valves can be connected in series for independent multiple single acting cylinder operations.
