Clamped single flap swing check valve is a kind of ultra-thin check valve, which has the advantages of simple structure, beautiful appearance, light weight, easy installation and so on. The flap of the check valve opens under the fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure of the inlet side is lower than that of the outlet side, the valve flap closes automatically under the action of fluid pressure difference, its own gravity and other factors to prevent backflow of fluids. Mainly used in water supply system, petroleum, chemical industry, metallurgy and other industrial sectors for the installation of space restrictions on the occasion.

Clamped single-flap rotary check valve structure length is short, its structural length is only 1/4 ~ 1/8 of the traditional flange check valve, small size, light weight, its weight is only 1/4 ~ 1/20 of the traditional flange check valve, flap closure fast, water hammer pressure is small, horizontal pipeline or vertical pipeline can be used, easy to install, smooth flow path, fluid resistance is small, the action, sealing performance is good, flap trip Short, closing impact is small, the overall structure, simple and compact.

Clamped single flap swing check valve adopts short structure size and single flap swing design, with no leakage, horizontal installation, good sealing performance, small linear vibration, small pressure drop and zero seat ring wear advantages. Clamped single-flap rotary check valve adopts short structure size and single-flap rotary design, compared with the traditional check valve, this series of valves have no leakage, horizontal installation, good sealing performance, small linear vibration, small pressure drop and zero seat wear advantages, especially when the valve is installed horizontally when the valve is open pressure.
