Description
The Spartan Valves ME7530W is a 24-volt, two-position zone valve engineered for reliable hydronic and HVAC system flow control. Featuring spring-return (S/R) operation and a normally closed (N/C) configuration, this valve automatically returns to its closed position upon loss of power — providing a built-in fail-safe for system protection. The stem-down orientation suits a wide range of piping installations, and the included 36-inch cable lead offers convenient wiring flexibility during installation.
