Structure and Application
**0X
remote control float valve is consisted of main valve, needle
valve, ball valves, float ball valve, miniature filters and other
components to form the hydraulic control system, after being set
down ,the liquid level can be controlled automatically.
The product is directly controlled by liquid level without other
device and energy, so it's easy to maintenance, liquid level
control is highly accurate, the valve is easy to get rid of the
influence of water pressure, and the sealing is reliable.
This remote control float valve is widely used in liquid level
control of water tower, water pool and other facilities in water
supply network system of high-rise buildings, living areas and
etc.
Pressure level: PN*0, PN*6, PN*5
The diaphragm type: DN*0~DN**0
Working Principle
When
the water is supplied from the water inlet end, the needle valve,
ball valves and float ball valve keeps open, the main valve opens,
when the water level rises to the set position, float ball rises,
floating ball valve close, the increased hydraulic pressure
promotes the main valve closed. When the water level drops, the
float ball valve opens again, the hydraulic pressure
reduces
and
the main valve ,the water continues to supply until the water level
reaches to the set height.
