Stainless Steel Normally Open Solenoid Valve 110V 3/8" FNPT
This normally open solenoid valve is built for low-pressure applications where fail-safe open operation is critical. Direct-lift diaphragm construction allows the valve to open from zero pressure, making it suitable for gravity-fed systems, drain lines, and emergency shutoff applications where loss of power must default to open flow.

Application Guide
This normally open solenoid valve is designed for RO system drain lines, low-pressure feed systems, fail-safe shutoff applications, and any installation requiring open flow during power loss. The 304 stainless steel body and BUNA-N diaphragm handle potable water, brackish water, and most non-corrosive fluids up to 150°C. The 3/8" FNPT port threads into standard pipe fittings and connects to tubing via threaded adapters. Direct-lift design operates reliably from zero pressure, making it ideal for gravity-fed tanks and atmospheric drain applications where standard pilot-operated valves fail to function.
