规格
  • Zone valves are used to automatically shut-off the flow, redirect or modulate hot and chilled water in hydronic heating and air conditioning systems. The motorized three-way diverting / mixing valve permits two position diverting or three-way mixing with 3-wire floating outdoor reset controller for injection mixing. The motorized three-way bypass valve permits a system to operate with a continuous flow regardless if the zone valve is in the open or in the by-pass position. The high flow and high close-off performance characteristics of these zone valves, combined with the compact size, makes them particularly suitable to fit inside baseboard or directly in fan coil units. The 6442 and 6443 series motor drives for 40 seconds. Power is then dropped by an internal switch. Power is required to drive in both directions. These valves are used in all types of systems because of the following characteristics: • Zero leakage across the valve • Quick opening and closing valve operation • Operates at very high differential pressures • Loss of power stays in last position (open, closed or mid-stroke) • Low pressure drop through the valve • Union connections for simple installation and removal The 6442 and 6443 series is available with NPT male, sweat or press union connections. Presscon™ copper tail-piece with union nut makes installation and maintenance fast, easy and efficient. Special slots in the EPDM O-ring allows fluid to leak during system testing if unpressed and provide a perfect leak proof seal when completely pressed.
