Swing Check Valves

Swing Check Valves Introduction:

The Hanno Valve Swing Check Valves adopts an internal rocker arm rotary opening structure. All the opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body. Except for the sealing gasket and sealing ring used in the middle flange, there is no external leakage point as a whole. The rocker tube and valve release connection of the Swing Check Valves adopt a spherical connection structure, which gives the valve a certain degree of freedom within a 360 degree range and appropriate micro position compensation. Suitable for clean media, not suitable for media containing solid particles and high viscosity. Can be used for various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and urea. Mainly used in pipelines for petroleum, chemical, pharmaceutical, fertilizer, electricity, and other industries.

‌The main features of Swing Check Valves are good sealing performance, simple structure, small volume, light weight, low fluid resistance, suitable for all kinds of working conditions of the pipeline system. ‌The Swing Check Valves depend on the pressure of the medium to open and close, when the medium is forward flow, the valve disc is lifted by the fluid, the medium flows through; When the medium is back flow, the valve disc falls under the action of its own gravity and the reverse thrust of the fluid, and closes the valve port to prevent the medium backflow.
