H142X hydraulic water level control valve with automatic opening and closing of the pipeline to control the water level, applicable to industrial and mining enterprises, civil buildings in a variety of water towers or pools in the automatic water supply system, and can be used for atmospheric boiler circulating water supply control valves, hydraulic water level control valves are small in size and easy to install, enabling high sensitivity, head loss is small without the phenomenon of water hammer. As a result of small float control can greatly improve the utilization rate of the water tower, for the new water tower due to the reduction in the volume of the float and make the upper part of the water tower left to the float free floating height required to reduce the cost of reducing the water tower, to overcome the old rod float valve large size, easy to damage, low working pressure, a large number of overflow and other shortcomings of the new water tower and update the old float valves are more desirable and more appropriate products. When the water level in the pool or water tower falls, the float valve is opened to drain the water, the inlet pipe pressure water will be the piston inside the valve to raise the sealing surface is open, the valve is open to the water supply, when the water level rises to the control valve, the float valve is closed, the piston will move down to the sealing surface closed, the valve is to stop the water supply.
Product Features
- Utilizing hydraulic principles for control, featuring a novel and rational structure.
- Operates smoothly and reliably. Within the specified operating pressure range, there is no water hammer impact.
- Lightweight and compact.
- Easy to install and maintain.
