Hydraulic and Pneumatic Valves: Speed Control

The Slow Return Kinechek controls the speed with which a load pushes on a plunger rod. A fixed restricting orifice built into a unit’s internal flow passages slows the automatic extension of the plunger rod. Extension time can range from 6 to 22 sec/in. of stroke. The nonadjustable return time depends on the orifice size. The leakproof and fully adjustable units come in ½, 1, 2, and 3 in., with a maximum capacity of 1,200 lb.
