Lockup device, manual operation, in order to prevent misoperation, valve can be equipped with padlock device.
Anti-static structure, when a fire break out, the metal seal forms to prevent large leakage of media.
Valve body and stem can finish emergency injection seal, through the grease injection valve, the stop-leak compound can achieve a short-time
seal, therefore buying time handling the scene.

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.
It is mainly used for storage and transportation of oil and gas in the chemical industry, metallurgy, paper making, food processing, shipbuilding and other industries, used to open or close, and with pneumatic and electrical devices can also achieve the long-distance operation, to ensure personal safety.
The structure is simple & compact with: smooth flow passages, high accuracy in flow characteris- tic curves, stable & reliable, economically practical, and easy to maintain. Based on a conventional type, it is designed and developed through modular extension which is capable of producing special structures such as: the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve for user selection.
