Technical Overview & Engineering Specifications
The Third-Party Pre-Shipment Inspection (SGS, BV, TÜV) for Valve Export Orders 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.

Pre-Inspection Meeting & Quality Plan (ITP) Alignment
Prior to inspector arrival, Baoming agrees upon a detailed Inspection & Test Plan (ITP) referencing exact customer technical specifications, governing standards (ISO/EN/AWWA), and sign-off witness hold points.
Witnessing Hydrostatic Shell & Seat Tests in Real Time
Third-party inspectors physically witness hydrostatic testing on our automated test benches. Pressure gauges with valid calibration certificates are logged, test hold durations timed, and zero bubble leakage confirmed on every audited unit.
Coating Thickness (DFT) and High-Voltage Spark Witnessing
Inspectors utilize magnetic thickness gauges across body, bonnet, and disc surfaces, followed by a 3000 V holiday spark probe to ensure 100% pinhole-free corrosion protection prior to crating.
