The Bellows Seal Gate Valve is a high-performance valve designed to ensure sealing integrity and prevent medium leakage. It utilizes bellows seal technology to effectively block fluid leaks that could cause environmental pollution or safety hazards. This valve is suitable for use in steam, thermal oil systems, heat exchangers, and other high-temperature, high-pressure fluid control applications. Its compact structure and easy maintenance offer long-term reliable sealing performance.

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 dual-plate wafer check valve features two semicircular, spring-loaded valve discs mounted on a central vertical pivot. When the valve opens, the force of the fluid and the spring act at the center of the disc, causing it to open from the base first. This design minimizes wear on the seal during opening, enhancing its durability. As the flow decreases, the discs slowly move back towards the seat due to the spring's force, ensuring a gradual closure. During backflow, the increased force on the discs leads to a faster closure, effectively reducing the risk of water hammer and hydraulic shocks. The spring’s force closes the top end of the disc first, preventing damage at the disc's base and prolonging the seal's lifespan.

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.
