Product Overview

The BS 5153 Swing Check Valve Metallic Seat PN16 is an industrial-duty, metal-to-metal seated non-return valve manufactured to BS 5153 — the definitive British Standard for cast iron check valves. Designed for applications where resilient-seated swing checks reach their limits — higher temperatures, oil-based media, abrasive service, and fire-safety-sensitive installations — the Model 2120 features a GGG50 ductile iron body, gunmetal (bronze) metallic seat ring, ductile iron disc with precision-machined seating face, stainless steel SS304 swing arm and hinge pin, bolted bonnet with EPDM gasket, EN1092 PN10/PN16 flange connections, and 100% FBE coating on all surfaces. Available DN50–DN300. Manufactured by Jingda Valve. Each valve individually tested to BS 5153 / EN 1074 requirements.

BS 5153 is the UK and Commonwealth reference standard for cast iron swing check valves, parallel to BS 5163 for gate valves. It governs materials, dimensions, pressure-temperature ratings, testing, and marking. Specifying a BS 5153 check valve — rather than a generic "cast iron check" — gives consulting engineers, water authorities, and procurement teams the documented assurance of a standardised, tested, and traceable product from a qualified manufacturer.
