Pressure surges in Oil and Gas applications cause problems that can include back-flows leading to contamination of service fluids and potential damage to pipelines, process units and vessels. This gives rise to the need to protect systems against this eventuality.

Check Valves, or non-return valves, provide this function in all product flowlines and service lines on Surface and Subsea installations. Their duties can include: Injection, Control and Isolation functions, as well as system protection.

BEL Valves manufactures Check Valves in NB sizes, ½” to 24’’, and larger, for Pressure Classes ANSI 150 to 4500 and API 2,000 to 15,000psi. They are available in Flanged, Butt Weld, Socket Weld, Hub Connectors and other proprietary connections and are designed to API 6D and 6A. Additionally, BEL Valves’ Check Valves are tested and accredited to API 6A Appendix F PR2 and API 17D hyperbaric. They are available in Standard and Exotic Materials, with appropriate Trims, including Low Temperature Carbon Steels and Alloys. In critical applications enhanced corrosion resistance is achieved on the sealing surfaces by cladding with stainless steel or Inconel and all materials meet NACE specifications.
