Brand: Festo

Precision one-way flow control valve GRP-160-1/8-AL

The Festo 542023 is a manual one-way flow control valve featuring G1/8 pneumatic connections on both ports and a rotary knob with a scale for the adjusting element. Constructed with a PA-reinforced housing and configured for sub-base mounting in any position, this component operates within a pressure range of 0 bar to 8 bar and ambient temperatures from -10 °C to 50 °C using compressed air or inert gases. It achieves a standard nominal flow rate of 75.8 l/min in the flow control direction and 245 l/min in the non-return direction, with LABS conformity under VDMA24364 Zone III and operation without oil lubrication.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
