Bronze threaded spring foot valve with BSP or NPT female connections, bronze body and disc, 304 stainless steel spring and filter mesh, and EPDM sealing rings. Available in sizes from 1/2″ to 2″, with a non-shock working pressure of up to 2.0 MPa.
Bronze threaded spring foot valve designed to prevent reverse flow and maintain pump priming in water supply, irrigation, marine, plumbing and general industrial pumping systems. The integrated filter mesh helps prevent debris and solid particles from entering the pipeline, pump or other downstream equipment.
The valve features a durable bronze body, bonnet and disc, together with a 304 stainless steel spring and filter mesh. The spring-loaded disc closes automatically when the pump stops or the flow reverses, while the dual EPDM sealing rings provide reliable sealing performance.
BSP or NPT female threaded connections are available to meet different installation requirements. Standard sizes range from 1/2″ to 2″, with a maximum non-shock working pressure of 2.0 MPa and an operating temperature range from -20°C to 120°C.
Lead-free bronze material, customized body marking and OEM packaging are available upon request.
