Detailed Product Description

KHW Series zone valve are applied to control room temperature by controlling the switch on and off for the central air conditioner system and cooling or heating system pipe. The control valve is driven by one-way synchronous machine of stagnant magnetism and it is spring reset. The valve is closed when it stops working. While it works, the temperature control will give out an open signal. Then the motorized valve will put through the alternating current to open the valve. The cooling or heating steam will then flow into the fan coil to supply the cool or heat for the room. When the room temperature reaches the set temperature, the temperature control will let the electric valve cut off the power. And the return spring closes the valve to prevent the water from flowing into the fan coil. Opening or closing the valve always keeps the room temperature in the range set by the temperature control.
