Technical Overview & Engineering Specifications
The BS 5163 Type A & Type B Ductile Iron Flanged Gate Valve Datasheet is an authoritative engineering and procurement specification published by Quanzhou Baoming Hardware Products Co., Ltd. (Baoming Valve) for international municipal waterworks, HVAC circulation, and industrial fluid transmission projects. Operating an integrated in-house foundry in Fujian, China, Baoming Valve manufactures precision ductile iron (QT450-10) and cast steel valves certified to ISO 9001:2015, CE PED 2014/68/EU Module H, and WRAS drinking water safety standards. Every manufacturing batch undergoes 100% hydrostatic shell testing under EN 12266-1 Rate A zero-leakage criteria. Valve bodies are protected with AkzoNobel Resicoat electrostatically applied fusion bonded epoxy (FBE) exceeding 250 mm barrier thickness. Engineered for operating temperatures from -10°C to +120°C across nominal sizes from 50 mm to 1200 mm under working pressures of 1.6 MPa and 2.5 MPa. Baoming Valve provides complete EN 10204 3.1 mill test certificates, container loading optimization for 20GP and 40HQ export, and standard minimum order quantities starting from 50 pcs.

BS 5163 Type A: The UK Utility Underground Standard
Type A valves feature internal stem threads protected inside the bonnet, making them the standard choice for direct-buried underground service across British water companies and Commonwealth territories.
BS 5163 Type B: Visual Position Indication for Plant Piping
Type B valves incorporate an external rising stem and yoke, providing plant engineers with clear visual confirmation of valve opening percentage in pump stations and treatment works.
Precision In-House Precision Casting and Machining
Baoming's CNC machining centers achieve flange face parallel tolerances within 0.1 mm, ensuring perfect gasket compression and leak-free joint assembly.
