APPLICATION MV03 series floating/modulating valves are widely used in central air-conditioning cool/heat water system. It can accurately control the flow of cool/heat medium depending upon the requirements of the given application, and can not result in sudden change of temperature and to control the room temperature accurately. The valve is driven by bi-directional motor, which is connected with the floating thermostat by common, open and close terminals. The floating thermostat will continuously collect the data and make processing, and send out control signals to operate or stop the motor so as to modulate angle of the valve. Then the chilled/hot water will enter into the fan coil, and cool/heat air will be supplied to the room. When the room temperature reaches the set-point. The thermostat will make the valve power off. So the opening angle of the valve will be always at the best state, and the room temperature will be kept within the set range of the thermostat. If the controller for the valve is without overtime protection function, the timing protection device can be selected to assemble in the valve. With this timing protection device, the life of the motor will be extended. Two types of MV03 series floating/modulating valve: 2-way and 3-way. The sizes:1/2?3/4?1攁nd 11/4? There are 11 kinds of specifications classified by the access type and the fluid characteristic. There are also different pipe connection for your selection: BSP (G), NPT (N), SWEAT(S),INVERTED FLKARE (F),etc. The base and cover of MV03 series floating /modulating valve is used flameproof engineering plastic. Ball valve plug is used to control the fluid. It has the advantages of large flow rate, high differential pressure, low noise, stable and dependable performances. It provides superior ease of operation and can maintain and regulate high volume, high pressure, high/low temperature flow and high humidity condition often appeared in concealed fan coil unit. FEATURES:  Bi-directional floating proportional control;  High precision and sensitivity of temperature control;  Various AC voltages for selection, such as 24V, 110V and 220V,etc;  Timing protection device (for 24V working power supply, it can be assembled for optional), to ensure motor reliable and durable life;  Built-in electronic card (24V working power supply) can receive 0~10V (for model MV03匓) or 4~20mA (for model MV03匛C) DC input control signal, and provide proportional control;  The valve actuator and valve body is used tight lock connection. The actuator can be installed after the installation of valve body. It has flexible and convenient assembly.
