• The QS push-in fittings and captive seals paired with the robust, metal design enables a reliable and efficient installation that can be rotated or swivelled through a 360° axis


• Simple and fast mounting with QS fittings


• The valves are operated with a screwdriver (slot)


• Wide operating temperatures


• Threaded and tube connection type options can be found within the GRLA series


• Depending on the choice of valve from the series a precise setting can be obtained, which range from slow, medium or fast piston movements


• Manual actuation type

How do flow control valves work?

Flow control valves automatically adjust to variations in pressure and temperature in order to regulate speed, which is done through restrictions on the flow rate of compressed air. With a one-way flow control valve, the flow control function only works in one direction.
