100X Remote Control Float Valve

100X Remote Control Float Valve is a pilot-operated hydraulic control valve dedicated to automatic water level management of water tanks and reservoirs. Widely used in domestic water supply, fire protection water tanks, water treatment stations, municipal reservoirs and industrial water storage systems. Cooperated with float assembly, it can automatically control water inflow according to liquid level, realizing unattended automatic water supply.

The valve body is cast from high-strength ductile iron with good pressure resistance and structural stability. Standard pressure grades adopt PN10 and PN16 with flanged connection. The main valve is driven by fluid pressure and requires no external power supply. The on-off action of the main valve is controlled by a small external float pilot assembly.

Working principle: When the water level of the water tank drops, the float falls down, the pilot channel opens, the pressure in the main valve control chamber is released, and the medium pressure pushes the valve disc to open to start water replenishment. When the liquid level rises to the preset height, the float rises and closes the pilot passage. Pressure accumulates inside the control chamber, pushing the valve disc to close and stop water inflow automatically. The target water level can be adjusted flexibly by changing the installation height of the float.

This valve solves many defects of traditional small-caliber mechanical float valve. It can be used for large-diameter pipeline water intake, with large flow capacity and stable operation. Complete specifications cover DN50 ~ DN800. Applicable medium includes tap water, fire service water and clean industrial water, working temperature 0℃~80℃. The main valve is generally installed on the water supply pipeline outside the tank, and the float is placed inside the water tank.

Installation and operation notes: Install strictly following the flow arrow marked on the valve body. A Y-type strainer must be arranged upstream to prevent impurities from blocking the pilot pipeline. The float connecting rod should move freely without collision and jamming. Avoid installing the float in positions prone to water wave impact. This valve is used for liquid level automatic on-off control and cannot be used for continuous flow regulation.

All finished valves pass strict shell hydrostatic test, sealing test and linkage test with float assembly before delivery. Each unit is inspected to ensure sensitive response of pilot control and reliable closing performance when reaching target liquid level. It is an economical choice for large-capacity water tank automatic water replenishment projects.

With hydraulic self-driving, unattended automatic liquid level control, large available caliber range and convenient installation, 100X Remote Control Float Valve has been highly recognized by global water engineering contractors. Our factory can provide different flange standards and customized anti-corrosion coatings to meet diversified procurement demands of water supply and fire protection projects.
