The Cryogenic Gate Valve is a type of equipment used for full opening and full closing operations. The opening and closing element of the low-temperature gate valve is a gate plate. The movement direction of the gate plate is perpendicular to the flow direction of the fluid. The gate valve can only be operated in full opening and full closing positions, and cannot be used for regulation or throttling. The gate plate has two sealing surfaces. The most commonly used type of gate valve has two sealing surfaces forming a wedge shape, and the wedge angle varies with the parameters.
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 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.
