　    Kitzm building automatic control valves are used in commercial, industrial, medical and civil buildings. They can automatically control the liquid and gas in the heating and cooling central air-conditioning terminal coils to form a temperature control system to achieve constant control of the indoor temperature of the building, commonly used valves are: electric two-way valve, electric proportional control valve, self-operated control valve, etc...

Selections of automatic control valve for building air-conditioning system

1, chilled water unit, temperature control design electric two-way valve;

2, a stop valve is installed at the front and rear of the electric two-way valve;

3. pressure difference bypass valve between collector and manifold;

4. collection and manifold inlet and return pipe butterfly valve

5, horizontal main pipe electric butterfly valve;

6, air handling unit gate valve, filter, electric two-way or three-way valve

7, fan-coil electric two-way valve (VB7200)

Note: Generally, when temperature control is used, you can directly choose the electric two-way valve with a 5-piece set to meet the automatic temperature control. There is no need to use an electric regulating valve with a thermostat, of which the cost is higher.　　

Selections of valves for building air-conditioning pipes　　

1. butterfly valve for chilled water unit and cooling water inlet and outlet;

2, the butterfly valve and filter before the water pump, the check valve and butterfly valve after the water pump;

3. difference pressure bypass valve between collector and manifold;

4. collection and manifold inlet and return pipe butterfly valve

5. Horizontal main pipe butterfly valve;

6, air handling unit gate valve, filter, electric two-way or three-way valve

7. Fan-coil gate valve (or electric two-way valve)

Note: Generally, when butterfly valves are used, handle butterfly valves (D71X, D41X) are used when the diameter is less than 150mm; worm gear butterfly valves (D371X, D341X) are used when the diameter is greater than 150mm.
