Introduction to Hydraulic Water Level Control Valve

The water level control valve is suitable for automatic water supply systems in various water tanks (pools) in industrial and mining enterprises, civil buildings, and can also be used as a control valve for boiler feedwater systems.

Working Principle of Hydraulic Water Level Control Valve

When the water level in the water tank or pool drops, the float valve opens to discharge water. The water pressure inside the pipe lifts the valve plug, sealing the valve, and the valve opens to supply water. When the water level rises to the control level, the float valve closes, the water pressure decreases, the valve plug seals the valve, and the valve stops supplying water.

Technical Parameters of Hydraulic Water Level Control Valve

Performance Features of Hydraulic Water Level Control Valve

Uses hydraulic pressure control, with a reasonable structure.

Stable operation. It can withstand the specified operating pressure without water hammer.

Light weight, small size.

Easy to install and maintain.

Installation Methods and Precautions for Hydraulic Water Level Control Valve

The hydraulic water level control valve should be installed vertically on the water pipe, and the control pipe, valve, and float valve should be connected tightly to the valve. The water level control valve and the water pipe should be connected with H142X-4T-A as 0.6MPa standard flange; H142X-10-A as 1MPa standard flange. The water pipe diameter should be greater than or equal to the valve diameter, and the outlet should be lower than the float ball valve. The float ball valve should be installed at a distance of more than one meter from the water pipe, and the water pipe should be higher than the water level by about one meter to prevent water from flowing back. When installing the valve, the float ball valve should be installed at the same level as the water tank. The valve should be installed with a sufficient air gap to prevent water from flowing back. To prevent impurities and sand from entering the valve and causing malfunction, a filter should be installed.
