Description
● Bi-directional floating
proportional control.
● High precision and sensitivity of temperature
control.
● Various AC voltages for
selection, such as *4V, **0V and **0V,etc.
● Timing protection device (for
*4V working power supply, it can be assembled for optional), to
ensure motor reliable and durable life.
● Built-in electronic card (*4V
working power supply) can receive 0~*0V (for model KMV…B) or 4~*0mA
(for model KMV…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 (KMV..B/C without this function).
KMV 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 turn 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 KMV series floating/modulating valve: *-way and
*-way. The sizes:1/2”,3/4”,1”and *1/4”. There are *1 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 KMV 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.
