● 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.

It is mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc. to transport high viscosity media that solidify at room temperature. The insulation jacket of BJ45W DC jacket insulation globe valve is welded between the two flanges of the valve, and there are two connection ports for the insulation jacket on the side and bottom of the valve. DC insulation globe valve is particularly suitable for pipelines in the chemical and fertilizer industries, and the inclusion of steam in the jacket can prevent the crystallization of the medium. Insulated globe valves are widely used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc.
RAYS bellows sealed globe valve adopts international advanced technology and double sealing design. It has the characteristics of high-performance elastic metal bellows and extremely long expansion fatigue life. Pipe shut-off valves: improve the use of energy efficiency, increase the safety of production equipment, reduce maintenance costs & frequent maintenance, and also provide a clean & safe work environment. Bellows sealed globe valve are suitable for class 150~2500, working temperature -46°C~538°C pipeline. Using carbon steel, stainless steel and other different main materials can be suitable for various media. The optional drive devices are: hand wheel, electric, pneumatic, etc. Bellows sealed globe valves are suitable for pipelines under various working conditions in petroleum, chemical, pharmaceutical, fertilizer, electric power, and other industries.
The Comodity Cast Steel Gate Valve is mainly composed of valve body, valve cover, valve wedge, valve seat and valve stem. The two sealing surfaces are wedge-shaped gate valves. The purpose of the wedge is to improve the auxiliary seal load, to achieve both high medium pressure sealing and low medium pressure sealing. The valve body of the wedge valve is provided with a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
