1/2" Sweat 2-Way Zone Valve

APPLICATION:
The M Series zone valves provide on/off, normally closed control in closed hot or chilled water Hydronic systems. The valves can be used in a wide variety of applications, primarily designed for use with fan coils, radiators, convectors, air handlers, heat pumps and radiant systems. The valve is driven by a hysteresis synchronous motor with spring return.

NOTE: Not for use in open systems or closed systems with a high content of dissolved oxygen. Installations must be a noncondensing application.

MATERIALS Valve Body: Forged Brass Seal Material: EPDM Chassis and Cover: Fire-retardant ABS Engineered Plastic
