Bronze threaded swing check valve with BSP or NPT female connections, metal-to-metal sealing, bronze body and stainless steel pin. Available in sizes from 1/2″ to 2″, with a non-shock working pressure of up to 2.0 MPa.
Bronze threaded swing check valve designed to prevent reverse flow in water supply, plumbing, marine, HVAC and general industrial piping systems. The internal clapper opens automatically with forward flow and closes when the flow stops or reverses, helping protect pipelines and equipment from backflow.
The valve features a durable bronze body, bonnet and disc, together with a brass clapper and stainless steel pin. Its metal-to-metal sealing structure provides reliable performance under demanding working conditions.
BSP or NPT female threaded connections are available to meet different market requirements. Standard sizes range from 1/2″ to 2″, with a maximum non-shock working pressure of 2.0 MPa. Lead-free bronze material, customized marking and OEM packaging are available upon request.
