Brass & bronze check valve
GH-4007 Bronze swing check valve
The bronze swing check valve is a durable flow control device designed to prevent reverse flow in pipelines using a hinged disc that swings open under forward fluid pressure and closes via gravity or backpressure when flow stops or reverses. Constructed from corrosion-resistant bronze alloy, it excels in harsh environments such as marine systems, chemical processing plants, and steam applications, withstanding temperatures up to 110°C and pressures of 16 Bar. The valve’s full-port design minimizes flow restriction and pressure loss, while its bidirectional sealing capability—available with metal-to-metal seats for abrasive media (e.g., steam, slurry) or elastomeric seals (EPDM/NBR) for corrosive fluids—ensures leak-tight performance. Ideal for horizontal or vertical installation, it features a stainless steel hinge assembly for longevity and rapid closure to prevent water hammer. Commonly used in shipboard seawater/fuel systems, industrial cooling lines, and oil/gas pipelines, this valve combines low-maintenance reliability (thanks to bronze’s resistance to scaling and dezincification) with compliance to ANSI, DIN, and ISO standards, making it a versatile solution for demanding applications requiring robust backflow prevention and operational resilience.
