Description

1/2"–2" Normally Open Stainless Steel Steam Solenoid Valve – NOSUS


The NOSUS Series is a 2/2 way normally open stainless steel steam solenoid valve designed for applications where the valve must remain open until electrically energised. Featuring a pressure-assisted piston design with a forged 316 stainless steel body, the NOSUS range provides reliable control of steam, hot and cold water, air, gases and light oils at temperatures up to +185°C. Available in sizes from 1/2" to 2" BSP with optional NPT threads, these valves are ideal for fail-safe installations, steam distribution, process heating and industrial fluid control systems.
