Float valve uses a sub-valve
(floating ball switch) to control the main valve. When the water
level elevates to the full water level defined by sub-valve
(floating ball switch), the sub-valve (floating ball switch) closes
and back pressure inside the main valve accumulates rapidly, which
pushes the piston valve reversely to close. By this mechanism, the
float valve can thus control the water level. In order to save space
inside the pool and for easy maintenance, it is recommended to
install the float valve outside the pool.

Float valve closed
state
Float valve open state
| At full water level, pressure
accumulates in the pressure chamber and pushes the gate reversibly. |
At
low water level, pressure in pressure chamber dissipates, and water
pressure inside the pipe
pushes the gate open. |
The working pressure should be
greater than 0.3 kgf/cm2 , please check the pressure
before installation.
Please remove impurities or metal
dusts inside the pipe thoroughly. If possible, please add
filter to prevent pipe blocking.
When the flow rate is
insufficient, please avoid installing the valve up-side down
(installing the inlet upward).
Please
utilize this valve with high pressure floating ball
switch. | |
Special order is
needed for size over 14" or
particular dimension.
Please refer to MULTI-FUNCTION
AUTO-CONTROL
VALVES for valve body
material, working pressure and
flow. |
