The slow-closing check valve opens and closes the valve disc automatically due to the flow of the medium, and is a type of automatic valve used to prevent the backflow of the medium. It is mainly used to prevent backflow of the medium, prevent the reverse rotation of pumps and drive electric motors, and release the medium in containers. The check valve can also be used in pipelines that supply supplementary pressure to auxiliary systems where the pressure may rise above the system pressure.
RAYS cast steel check valves are designed and manufactured to provide maximum service life and dependability. All check valves meet the design requirements of American Petroleum Institute standard API600 & 6D.BS EN 13709 and generally conform to American Society of Mechanical Engineers standard ASME B16.34. Valves are available in a complete range of body/cover materials and trims.
The API 6A High Pressure Slab Gate Valve is specially designed for high-pressure pipeline systems in industries such as petroleum, natural gas, and chemical engineering. It features a valve body made of high-quality alloy steel, which is precisely machined and rigorously tested to ensure reliable performance under high pressure, high temperature, and corrosive medium conditions. The unique flat gate plate design enables two-way sealing, allowing for flexible opening and closing with low flow resistance. It is an ideal choice for long-distance pipelines, refining and chemical plants, and high-pressure fluid control systems.
