● 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.

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 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 single driving double ball valve is a special ball valve design, which combines two ball valves together, but is operated by only one drive device. This design is usually used in situations where two parallel pipelines need to be controlled or isolated at the same time. The design and application of single drive double ball valves need to consider specific process requirements and operating conditions to ensure its long-term stable operation and system safety.
