The Bell & Gossett Snap Zone Valve is a compact four-wire thermoelectrically operated on/off zone valve designed heating and cooling systems. Featuring an innovative compact design and an adapter ring that allows for the actuators to be installed in any 360-degree position, the Snap Zone Valve can fit under baseboards or in other tight spaces. A push-button actuator facilitates one-handed installation and permits wiring in any direction. A visual indicator provides quick and easy recognition of which valves are energized and a replaceable plunger assembly allows for internal removal without removing the valve from the system.
