Air Return Speed Controller

Air return Rate control adopts the fully closed structure, action accurate and uniform, the piston rod can be any stops on the stroke, realized efficient feed function step by step, improved the Frl unit machining precision. When the piston rod is pressed, hydraulic oil under pressure outflow from the adjustable overflow oil hole, provides the whole stroke with a constant feed control precision. By rotating the end of the outer shell outer adjustment knob can realize the adjustment of the feed speed. Fixed aluminum base makes turnstile gate easier to install and adjust knob to feed control more convenient, at the same time under the condition of temperature difference will not affect the steady speed function.
