Product Description

Company Profile

Specification

Working Principle:
It relies on the force generated by the medium flow itself in the pipeline to automatically open and close. When the medium flows forward, the pressure of the medium pushes the spherical disc (such as a rubber-coated ball) to move, opening the valve and allowing the medium to flow smoothly. When the medium stops flowing or reverses, the disc returns to the closed position under the action of gravity and medium pressure, tightly fitting the valve seat to prevent backflow.

Applications:

Water Supply and Drainage Systems:
Installed at the outlet of water pumps to prevent backflow and water hammer damage. Widely used in cold water, hot water, industrial and domestic sewage networks, playing a crucial role in sewage treatment plants and urban water supply/drainage systems.
HVAC Systems:
Used to prevent medium backflow in air conditioning circulating water systems, ensuring normal system operation and maintaining stable water flow and pressure.
Industrial Pipeline Systems:
Applied in pipeline systems across industries such as chemical, petroleum, pharmaceutical, and food and beverage to control the unidirectional flow of fluids, preventing backflow from damaging processes and equipment and ensuring production safety and stability.
