GRLA-1/4-QS-8-RS-D

One-way flow control valves regulate the piston speed of pneumatic drives during advance and return strokes. This is done through suitable restriction of the flow rate of compressed air in exhaust air or supply air direction. With the one-way flow control valve GRLA, the flow control function works in one direction only (exhaust air or supply air), the non-return function works in the opposite direction. The flow control function creates an adjustable annular gap inside the valve. This gap can be increased or decreased by turning the knurled screw or slotted head screw. The required restriction can be set with the help of this adjustment component.
