This 304 flanged check valve is a swing-type non-return valve for 2\u2033, 3\u2033 and 4\u2033 flanged lines. A hinged disc swings open with forward flow and drops shut when flow stops or reverses \u2014 no power, no operator. The body, disc, arm and bonnet are cast 304 stainless steel (CF8), with a CF8M (cast 316) version made to order, sealed with a PTFE gasket.<\/p>\n

Every size is available with two flange standards: ASME B16.5 Class 150<\/b> for American-spec piping, or JIS B2220 10K<\/b> for Asian-spec plants. Smaller line? Our threaded swing check valve<\/a> covers 1\/2\u2033\u20133\u2033, the one-piece silent check valve<\/a> covers 1\/2\u2033\u20132\u2033, or browse all \u043e\u0431\u0440\u0430\u0442\u043d\u044b\u0435 \u043a\u043b\u0430\u043f\u0430\u043d\u044b \u0438\u0437 \u043d\u0435\u0440\u0436\u0430\u0432\u0435\u044e\u0449\u0435\u0439 \u0441\u0442\u0430\u043b\u0438<\/a>.<\/p>\n

Class 150 or JIS 10K \u2014 Which Flange?<\/h2>\n

The two standards use different bolt circles, flange diameters and raised faces, so they do not bolt together<\/b> \u2014 a Class 150 valve cannot be mounted on JIS 10K counter-flanges, or the other way around. The valve body itself is the same; only the flange drilling changes. Choose by the standard your piping already uses: ASME B16.5 Class 150 is the norm in US-spec plants, JIS B2220 10K in Japanese- and much Asian-spec equipment. If you are not sure, tell us when you request a quote \u2014 the face-to-face length is identical for both, so the choice never affects your pipe layout.<\/p>\n
