SZD Motorized Ball Valve

1.Size:DN15~DN80 2.Voltage:24VAC\110VAC\120VAC\220VAC 3.High temperature controlling precision and sensitivity

SZD series motorized valve is mainly used in the cooling & heating water systems, which can control and adjust the temperature of the medium precisely, and never leads to an intense change to it.

The valve is actuated by double-way actuator, the motor is connected with the floating thermostat via the public port, open port and close port. The thermostat collects and proceeds the present data, and then send the signals to the motor to make it work or stop, then decides the degrees of the openness and closeness of the valve, finally control the flow rate of the heating water or cooling water, supplying the room with warm air or clod air.

When the room temperature is up to the setting index, the motorized valve will be out of power and keep the temperature in the setting range. If the controller do not have the function of delayed protection, this valve can work with its special timer protection device, and lengthen the usage life.

Features:1. Controlling mode: Double-way floating & proportional control;2. High temperature controlling precision and sensitivity;3. 24VAC\110VAC\120VAC\220VAC are optional;4. Timer protection device to decrease the damages to the motor(24V power source is optional);5. Inserted IC(24V power source) can receive 0~10V or 4~20mA signal;6. After the installation of valve, connecting the actuator to it via fixed screws.
