● The bellows globe valve has a special sealed structure that prevents common issues like stem packing leaks.
● It improves material efficiency and equipment safety while reducing maintenance costs.
● The design ensures a clean and safe work environment by preventing leaks.
● The double seal design (bellows and packings) prevents leaks even if the bellows fail.
● It reduces energy loss and promotes equipment safety.
● The valve has a longer lifespan, requires less maintenance, and has lower operating costs.
● The durable seal ensures zero leakage from the stem for reliable, maintenance-free operation.
● The stem is treated for better resistance to corrosion and wear.
● The valve features an attractive design with a visible position-indicating stem.

When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
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.
The valve body is made of high-strength alloy steel or stainless steel, and is equipped with a precisely processed swing-type valve disc structure, enabling automatic control of the unidirectional flow of the medium. The optimized fluid dynamics design effectively reduces water hammer impact. The surface of the valve disc is clad with hard alloy to ensure reliable sealing under high-pressure and high-speed conditions. It is suitable for pipeline systems in industries such as petroleum, chemical engineering, and power.
