● 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.

The axial-flow check valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
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.
Triple Eccentric Metal Seated Butterfly Valve is the newly-developed long-life and energy-saving products. The sealing is metal to metal, which couldbe changed to be seal ring to metal, stainless steel plate and composite graphite to metal. Under the working condition of high temperature and high pressure, it still has a stable sealing performance. Our company adopts optimization design and new technology, so that the torque is small, gainning the point of energy-saving, labor-saving and reliable sealing performance, thus to ensure the high-reliability of corrosion-resistantance, stand fire and wear-resistantance. This product is widely used in petroleum, natural gas, piped gas and medicine, food industry, industrial environmental water treatment and shipping industry.
