Technical Overview & Engineering Specifications
The DIN 3352 F5 Resilient Seated Gate Valve (Long Body) Engineering Specification 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.

Retrofit Replacement for Legacy Municipal Networks
Across Europe, the Middle East, and Latin America, older waterworks pipelines frequently feature DIN 3352 F5 long face-to-face dimensions. Baoming's F5 resilient seated valves drop directly into existing flanged piping without pipe spool fabrication.
Extended Guidance Ribs for Heavy Flow Stability
The longer valve body accommodates reinforced internal guide tracks, ensuring the rubber wedge travels smoothly during opening and closing even under high flow velocities exceeding 3.5 m/s.
Traceability and Mill Inspection Documentation
Each valve is serialized and shipped with an EN 10204 Type 3.1 inspection certificate recording casting chemical composition, tensile elongation, and hydrostatic test charts.
