Import Brcv Series Bronze Swing Check Valves — Buy in Bulk from Supplier in China

The BRCV Series comprises bronze-bodied swing check valves with disc-type closure, manufactured for water, ethylene glycol and non-corrosive media service. Available nominal diameters run from DN15 to DN50 (one-half inch to two inches), rated at PN16 working pressure. The swing disc design permits full flow when open and relies on gravity and back-pressure to seat when flow reverses, a mechanism that generates lower pressure drop than lift-type alternatives in the same size range.

Construction follows bronze alloy castings with threads cut to BS EN 10226 (ISO 7) parallel or ISO 228 parallel standards depending on the specific variant ordered. The temperature envelope spans -5 degrees C to +85 degrees C, suitable for heating circuits, chilled water and glycol-based thermal transfer systems. Shell test pressure is 1.5 times PN16 (24 bar) and sealing test pressure is 1.1 times PN16 (17.6 bar), which are standard hydrostatic test multipliers for soft-seated or metal-seated industrial valves per EN 12266-1.

Installers in building services, maritime auxiliary systems and light industrial plants select bronze swing check valves for seawater resistance where dezincification-resistant (DZR or CDA 836) bronze is specified, though the exact alloy grade for this series is not stated. The ISO 228 connection standard implies parallel threads with 55-degree Whitworth form, requiring compatible flat-seal or O-ring fittings rather than taper-thread jointing compounds. Buyers should confirm with Zhejiang Banninger Fluild Control Co., Ltd. whether the -5 degrees C lower limit is a hard material limit or a recommendation to prevent ice-jacking in marginal freeze conditions.
