Cryogenic Gate Valve

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.…

Features & Benefits

·Long neck valve cover design: Extend the neck of the valve cover to reduce the transmission of cold to the operating mechanism and prevent the packing from freezing. The neck length is calculated and determined based on factors such as the thermal conductivity and heat dissipation coefficient of the material, ensuring that the temperature at the bottom of the packing box remains above 0 ℃. ‌

·Anti abnormal pressure rise structure: A pressure relief hole is installed on the inlet side of the gate plate. When the pressure in the valve chamber increases, gas can be discharged through the small hole to prevent the gate plate from tightly pressing the valve seat and causing it to fail to open. ‌
