Product description
Parameters

The swing check valve is installed at the outlet of the pump. When the pump is opened, the valve plate relies on the media flow and the force rotates around the pin shaft outside the valve seat to open automatically; when the pump is stopped, the valve plate relies on the medium backflow and the valve plate weight. A check valve that shuts itself off to prevent back flow of the media. The valve is widely used in petroleum, chemical, food, textile, papermaking, hydropower and other industries. It is used to cut back the flow of corrosive and non-corrosive gases and liquids, eliminate damaging water hammer, and protect pipelines and water pumps.

It is composed of three main parts: valve body, valve cover and valve flap. The rubber valve is made of steel plate as pressure piece and reinforced nylon cloth as substrate. It is wrapped with high-quality vulcanized rubber, and the sealing elasticity is good. Media isolation, valve seat ceramic spraying process makes the valve longer life.

The valve adopts full-flow area design, with small head loss, less accumulation of debris, and easy maintenance. It has a small valve opening stroke and high speed, and is mainly used for water supply and drainage systems. For the large-diameter DN ≥ 400 swing valve type rubber flap check valve, slow closing cylinder device can be used to divide the valve into two stroke phases: quick closing and slow closing. The stroke time of slow closing can be adjusted.
