Description
The GRLA-1/8-QS-4-D One-Way Flow Control Valve is an efficient pneumatic solution for regulating exhaust air in one direction while allowing free flow in the opposite. With a slotted screw adjustment and screw-in mounting, this valve provides precise control of actuator speed and pressure release.
Designed for QS-4 push-in connections and G1/8 threads, it supports a wide pressure and temperature range and operates reliably in cleanroom environments (ISO Class 4). Made from RoHS-compliant materials, including a rugged aluminum body and NBR seals, it’s ideal for automation, machinery, and other industrial pneumatic applications.
