Stainless Steel Flanged Swing Check Valve – 304 / 316L, Full Bore, API 600
The working principle of the Stainless Steel Flange Swing Check Valve is based on the flow direction of the medium and the automatic rotation of the valve flap. When the media flow in the right direction, the media pressure to promote the valve flap around the axis of rotation to the open position, the media through; when the media stop flowing or reverse flow, the valve flap in the role of gravity or spring (if any) automatically rotate back to the closed position, cut off the path of the media flow, to prevent the media backflow.

Performance Features:
Good sealing performance: the screw-opening design makes the valve flap close to the valve seat when closing, forming an effective seal.
Small flow resistance: when the valve is open, the flow path between the valve flap and the valve seat is unobstructed, and the flow resistance is small, which is conducive to the smooth flow of the medium.
Long service life: made of high-quality materials and advanced technology, corrosion-resistant, wear-resistant, long service life.
Precautions:
When installing the welded swing check valve, you need to make sure that the flow direction marking of the valve is consistent with the medium flow direction.
Sealing test should be carried out after installation of the valve to ensure that there is no leakage of the valve in the closed state.
In the process of use, the operating condition of the valve should be checked regularly, and any abnormality should be dealt with in time.
