Floating And Modulating Valves

Following are the Main Features of Floating and Modulating valves :-
a Bi-directional floating proportional control.
a High precision and sensitivity of temperature control.
a Various AC voltages for selection, such as 24V, 110V and 220V,etc.
a Timing protection device (for 24V working power supply, it can be assembled for optional), to ensure motor reliable and durable life.
a Built-in electronic card (24V working power supply) can receive 0~10V (for model KMVa B) or 4~20mA (for model KMVa C) DC input control signal, and provide proportional control.
a 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 (KMV..B/C without this function).

KMV series Floating and 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.
