Product Overview
Stainless Steel Flanged Swing Check Valve is a non-return valve used to allow flow in one direction and prevent backflow when the line pressure drops or reverse flow occurs. The swing disc opens automatically by flow pressure and closes by reverse flow or gravity.
Based on the product marking and nameplate, this valve is supplied in DN250 / 10" size with SCS14 body and disc material, RF flange connection, and JIS 10K pressure rating. The bolted cover construction allows access to the internal disc area for inspection and maintenance.
