True Union NSF Food-Safe Solenoid Valves – 110V, Normally Closed (½" & ¾")

Our True Union NSF Food-Safe Solenoid Valves are engineered for high-purity applications where safety, sanitation, and rapid serviceability are essential. Available in ½" and ¾" sizes, these valves feature NSF 61-G and NSF 372 certifications—ensuring they meet the strict requirements for drinking water and food/beverage systems.

Designed with true union sanitary connections, these valves allow fast, tool-friendly removal, system cleaning, and maintenance—ideal for environments that require routine washdowns or quick component replacement.

Offered in two coil configurations:

• Lead-wire coil versions (24" wire leads)

• Terminal-coil versions (quick-connect coil terminals)

Both variants utilize a high-temperature NEMA-rated nylon coil housing, rated for 100% duty cycle, and all models come as normally closed (NC) 110V units for dependable shutoff.

NSF Certified for Food, Beverage & Drinking Water

These valves carry:

• NSF 61-G certification (drinking water system components)

• NSF 372 certification (lead-content compliance)

Perfect for use in applications where hygienic handling and potable-water safety are required.
