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.

The hard-sealed butterfly valve is a newly developed long-life, energy-saving butterfly valve by our company. It consists of main components such as the valve body, butterfly disc, sealing ring, and transmission mechanism. Its structure is designed based on the two-dimensional or three-dimensional eccentric principle and features a new manufacturing process that accommodates both elastic and multi-layer hard-soft seals. This design reduces torque during operation, achieving energy efficiency and labor-saving benefits. At the same time, it ensures the valve's overall reliability in corrosion resistance, high temperature tolerance, and wear resistance. Common types of hard-sealed butterfly valves include wafer type, lug type, and flanged type butterfly valves.
RAYS manufactures high-quality fully welded ball valves, forged from premium materials with side-mounted balls. The valves are available in two designs: cylindrical and spherical fully welded bodies. RAYS is particularly known for its cylindrical valve bodies.
RAYS cryogenic ball valve with extended bonnet ball valve will bring you a huge gain in the field of cryogenic LNG service. Service temperature from -51° to -196°C (-59,8° to -320,8°F) with extended bonnet design.
