Technical Overview & Engineering Specifications
The UAE DEWA & ADDC Dubai / Abu Dhabi Water Distribution Valve Approvals 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.

DEWA Technical Prequalification Criteria
DEWA mandates that all isolation valves feature full ductile iron construction per BS EN 1563, stainless steel 316 stems, and high-purity EPDM rubber certified by WRAS. Baoming valves undergo 100% individual pressure testing witnessed by independent verification bodies.
Double Flanged Butterfly Valves for Trunk Mains
For diameters exceeding 300 mm up to 1200 mm, DEWA networks specify double eccentric flanged butterfly valves with stainless steel disc seats and adjustable retained body seals to facilitate in-line maintenance.
Digital Traceability & Testing Certification
Each valve shipped to the UAE includes laser-engraved QR codes linking directly to the casting heat number, pressure test log, and EN 10204 3.1 mill certificate.
