Festo 529421 Ms4-Lr-1by8-D5-As Pneumatic Pressure Regulator

Product Details

Festo MS4-LR-1/8-D5-AS Pneumatic Pressure Regulator – Part No. 529421 The Festo MS4-LR-1/8-D5-AS is a compact pneumatic pressure regulator from the Festo MS series, designed for reliable pressure control in compressed-air and inert-gas systems. It features a directly actuated diaphragm design, integrated pressure gauge, secondary venting, and return-flow capability for consistent downstream pressure regulation. The regulator has G1/8 pneumatic connections and provides an adjustable pressure regulation range of 0.3 to 4 bar. It supports an operating pressure range of 0.8 to 14 bar and delivers a standard nominal flow rate of up to 1,200 l/min. The rotary adjustment knob includes a locking function, helping prevent unintended pressure changes during operation. With its compact MS4 design, the Festo MS4-LR-1/8-D5-AS is suitable for pneumatic automation equipment, industrial machinery, air preparation systems, and compressed-air control applications. It can be installed in various mounting positions and supports front-panel or in-line installation.
