Definition: The Filter Piston Remote Control Float Valve is a type of hydraulic control valve to control the level of water tank or tower within scope, avoiding water overflowing or water at too low level.
Function: This type of valve is installed in the inlet conduit of water tank or tower. When the water level goes up to a given level, the float goes up to close up the float valve; when the water level drops, the float goes down to open the float valve.
Application: the valve is widely used in the inlet piping of water tank or tower of fire protection, municipal water supply and drainage systems, and industrial and mining enterprises, etc. It normally works as a water level control device.
Working principle:By adjusting on and off of the float valve, the main valve would be controlled to open and close up. When the water level goes up to a given level, the float goes up to close up the float valve. The water pressure inside piston control chamber is rising up to drive the main valve close up, and therefore stops supplying water. When the water level drops, the float goes down to open the float valve. The water pressure inside piston control chamber is lowering down to prompt the main valve open supplying water, and therefore keeps the water level in a predetermined height.
A. Non-effected from water pressure fluctuation, high degree of accuracy for water level control
B. Direct water level control by float valve, no need of other equipments and energy, easy handling
C. Piston type valve with reliable performance, intensive strength, and smooth action
D. Y-pattern wide valve body, low fluid resistance, large flow capacity.
E. Quick opening and slow close of the valve disc, no water hammer impact(adjustable on/off time)
F. Both inner and outer surface are coated with environmentally friendly coatings to ensure corrosion resistance and safety.
G. With self-equipped filter device to make the installation dimensions shortened by 40%, reducing installing room and saving the cost.
