Product Description

FESTO MS4-EM1-1/4-S Pneumatic On/Off Valve with Soft Start

The FESTO MS4-EM1-1/4-S (Part Number: 541259) is a premium electrically actuated pneumatic on/off valve belonging to the highly modular MS4 series. Engineered for optimal safety and efficiency in compressed air preparation systems, this valve features an integrated soft start function. This critical feature gradually builds pressure upon startup, preventing sudden pneumatic surges and protecting sensitive downstream components from mechanical shock and premature wear. Designed for robust industrial environments, it withstands a maximum operating pressure of 14 bar (210 psi / 1.4 MPa) and operates reliably in ambient temperatures up to +60°C (+140°F). Equipped with a standard G1/4 port size, the MS4-EM1-1/4-S ensures seamless integration into a wide variety of automated manufacturing and control applications.
