Application Fields:

  Check valve is for prevents the fluid from flowing back and ensures to flow in only one direction. It can be used to prevent the flow less from returning avoid pipe hammering. It is widely used in the food processing, beverage,wine,oil,cosmetics,pharmaceutical and chemical industries.

Operation Principles

  The working principle of the check valve is to realize automatic opening and closing by relying on the weight of the opening and closing parts (valve disc) and the medium pressure. When the medium flows in from the inlet end, the valve disc is pushed open by the medium pressure, and the medium can flow; when the medium flows back, the valve disc is closed by the dual action of its own weight and the backflow medium pressure, preventing the medium from flowing back.
