Professional Electrically Controlled Water Valve For HVAC Water System

3-way electric ball valve brass ball valve electrical valve for HVAC water system

SQ series motorized ball valves are widely used in central air-conditioning system. It can accurately control the flow of cool/heat medium in system, and can not result in sudden change of room temperature. The valve is connected with the thermostat. When the thermostat send control signals to valve, the motor willoperate, so the water will enter into the fan coil, the room temperature will change, when temperature reaches the set point, the thermostat will make the valve power off. The valve is at the best state, kept the room temperature in comfortable.

Features

Smooth flow, no clog

High flow capacity

Suitable for any specifications of fan coil unit.

Tight close, no leakage.

The power is cut off when the valve reaches the on/off position. This ensures long life service for the actuator.

The actuator cover adopts close strcuture which is resistive to humidity and ensures reliable operation for motor.
