The swing check valve is designed according to API6D specification and is suitable for crude oil and natural gas pipelines to prevent the medium from flowing backward. The fully open design can meet the cleaning ball passage and is convenient for pipeline maintenance. For large diameter valves, an optional buffer damping device can be used to delay the valve closing time to protect the sealing surface. We offer two main series of soft seal and hard seal.
