Description
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 can be connected in series for independent multiple single acting cylinder operations. Lever Operated D.C.V.
