What are the specifications and varieties of the central air conditioning electric valves

The electric valve is an important control device of the central air conditioning system, which is used for the interruption or regulation of the cold water / hot water of the fan coil unit in the air conditioning system. When the electric valve is in working condition, it receives the output signal of the DCS control system of the central air conditioner, and the valve is in the open state to convey cold water or hot water to the room. When the room temperature reaches the working requirement, the temperature controller sends the signal to the electric valve, so that the valve is closed.

The central air conditioning electric valve mainly includes the following products: electric two - pass valve, electric triple valve, electric butterfly valve, electric cut-off valve and so on. Different electric valves can be selected according to the requirements of different system control.
The basic characteristics of the electric valve in the central air conditioning
1. Ball valve adopts forging brass material and stainless steel stem.
2. Butterfly valves are sealed with natural rubber and no bubbles will be generated when they are closed.
3, electric actuator can be controlled by high and low voltage, and the application is flexible.
4, the external space occupied by the electric valve is small, and it can be installed close to the wall or install the valve first and then install the actuator.
