More Info
Zone valves are used to automatically shut-off the flow or redirect hot and chilled water in hydronic heating and air conditioning systems, and is UL listed for plenum installations. The motorized two position, on/off, spring return Z1 series actuator has an end mounted push button for quick installation to valve body. The actuator is equipped with or without auxiliary switch and configured Normally Closed or Normally Opened with wire or terminal connections. The zero leakage high temperature zone valve body Z2 series is 2-way straight through and the valve body Z3 series is 3-way diverting. The Z1 series actuator is easily attached by a push button lock and without tools.
The high temperature and high close-off performance characteristics of these zone valves, combined with the compact size, makes them suitable to fit inside baseboard or directly in fan coils units.
