Description

1 Inch Stainless Steel Steam Solenoid Valve – SUS25


The SUS25 is a 1" BSP 2/2 way normally closed stainless steel steam solenoid valve designed for reliable control of higher flow steam, hot water, air, gases and light oils. Featuring a pressure-assisted piston design with a forged 316 stainless steel body, it is suitable for continuous industrial duty and media temperatures up to +185°C. Its larger 22 mm orifice and high flow capacity make it ideal for steam distribution, process heating, sterilisation equipment and demanding industrial fluid control applications.
