Technical Overview & Engineering Specifications
The Industrial Cooling Tower Water Circuit Valve Sizing & Chemical Resistance 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.

Handling Aggressive Biocides and Scale Chemistry
Industrial cooling water cycles are heavily treated with oxidizing biocides (sodium hypochlorite, bromine) and phosphonates to prevent legionella and scale. Baoming butterfly valves utilize virgin EPDM and PTFE liners backed by stainless steel 316 discs that withstand chemical degradation.
Model 100X Automated Make-Up Water Level Control
Evaporative losses require continuous make-up water replenishment. The Baoming Model 100X hydraulic float valve modulates inflow to maintain tower basin water levels without overflowing, preventing water wastage.
Full-Flow Y-Strainers to Protect Heat Exchanger Tubes
Cooling tower basins scrub airborne dust and debris from atmospheric air. Installing Baoming GL41H Y-strainers with stainless steel perforated screens ahead of circulation pumps protects downstream shell-and-tube heat exchangers from fouling.
