Festo GRLA-3/8-QS-8-D Throttle Check Valve

The throttle check valve, also known as a one-way flow control valve, restrictor check valve, or flow control valve with check function, from manufacturer Festo with type number GRLA-3/8-QS-8-D is a pneumatic valve for controlling volumetric flow in one direction and simultaneously allowing free flow in the opposite direction. It has the dimensions 4 x 2 x 5 cm and weighs 0.06 kg. Throttle check valves are used in pneumatic systems to precisely adjust the speed of cylinders or other actuators by throttling the airflow in one direction while allowing free return flow. Typical applications are found in automation technology for speed control of drive elements and in mechanical engineering for optimizing cycle times and motion sequences.
