The dual plate 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.
Cryogenic Gate Valve is an opening and closing device used for fully opening and fully closing. The opening and closing component of ultra-low temperature gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces that form a wedge shape, and the wedge angle varies with parameters.
The Cryogenic Single-seat Control Valve is specially designed for low-temperature working conditions ranging from -196℃ to +80℃. It features an integral forged valve body structure and is equipped with a bellows seal assembly to ensure reliable sealing under extreme temperature conditions. The valve core is designed with a parabolic or equal percentage flow characteristic, forming a precise fit with the hardened alloy valve seat to achieve precise control of the medium flow. The product complies with IEC 60534-4 and GB/T 4213 standards, and is suitable for precise regulation of low-temperature media such as LNG, liquid oxygen, and liquid nitrogen. The pressure rating covers ANSI Class 150 to 900, and is widely used in key areas such as air separation equipment and low-temperature storage and transportation systems.
