Description

1½ Inch Normally Open Brass Steam Solenoid Valve 0.5–20 Bar – CS Fluid Power NOSA40

A heavy-duty, pressure-assisted piston operated 2/2 way normally open brass solenoid valve designed for very high-flow, high-pressure and high-temperature applications. The NOSA40 is a robust, long-life steam valve that remains open without power and closes when energised, making it ideal for fail-safe steam and thermal process control systems.
