HVAC Commercial Chilled Water & Boiler Systems
Dual plate check valves, butterfly valves, and differential pressure balance valves for HVAC chiller & boiler loops.
Targeted Valve Engineering for HVAC Commercial Chilled Water & Boiler Systems
Quanzhou Baoming Hardware Products Co., Ltd. (Baoming Valve) designs and manufactures heavy-duty ductile iron (QT450-10) and cast steel industrial valves specifically engineered for hvac commercial chilled water & boiler systems and related pipeline infrastructure. Certified under ISO 9001:2015, CE PED 2014/68/EU Module H, and WRAS drinking water safety protocols, our valve assemblies comply with AWWA C509/C515, EN 593, DIN 3352, and API 594 international design codes. For hvac commercial chilled water & boiler systems, our recommended configurations include resilient seated gate valves, double eccentric flanged butterfly valves, and 100X to 800X automated hydraulic control valves rated for nominal pressures of PN10, PN16, and PN25 across nominal diameters from DN50 to DN1200. Each valve undergoes 100% hydrostatic shell testing at 1.5x PN and seat testing at 1.1x PN to EN 12266-1 Rate A zero-leakage standards, with electrostatic AkzoNobel Resicoat fusion bonded epoxy (FBE ≥ 250 μm). We offer global EPC contractors full mill certificates (EN 10204 3.1) and optimized 20GP/40HQ containerized dispatch.
Recommended Valve Series & Specification Matrix
| Valve Type | Model Series | Pressure & Size | Key Engineering Benefit |
|---|---|---|---|
