The swing-type check valve is designed according to the API6D specification and is applied to the pipeline of crude oil and natural gas to prevent the medium from flowing backward. The fully open design can meet the cleaning ball passage and facilitate pipeline maintenance. For large diameter valves, optional buffer damping device can be used to delay the valve closing time to protect the sealing surface.
