SO-25109 Self-operated Low-pressure Relief Regulator
An energy-saving control valve without external energy sources can be widely used in gas sealing devices of nitrogen-sealed storage tanks for non-corrosive gases with a pressure relief range of 0.1 to 10 KPa and a working temperature not exceeding 150℃. It can also be applied to low-pressure or vacuum safety protection systems in industries such as ships, natural gas, oxygen production, and blowers. The structure is simple, installation and debugging are convenient, maintenance costs are low, the pressure regulation range is wide, and it can be adjusted in three grades within the range of 1.0 to 10 KPa. The response speed is fast, and the regulation accuracy is low.
Self-Operated Micro-Pressure Regulator does not require additional driving energy and is a kind of energy-saving control device; it is a specialized product for current most popular nitrogen sealing system of storage tanks.

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.
Designed specifically for industrial ventilation and gas transportation systems, it features a high-strength carbon steel or stainless steel valve body, equipped with a low-torque sealing structure, enabling efficient regulation of large flow of gas media. The optimized butterfly plate design is combined with wear-resistant sealing rings, ensuring reliable performance under harsh conditions such as high temperatures and dust. It is suitable for ventilation and dust removal systems in industries such as power plants, metallurgy, and chemical engineering
The valve disc of the Cryogenic Lifting Check Valve adopts a vertical lifting structure and is equipped with a cobalt-based alloy sealing surface. It can achieve rapid response and reliable sealing when the medium pressure changes. The product complies with BS 6364 and API 6D standards and is suitable for the transportation systems of low-temperature media such as LNG and liquid oxygen. The working pressure can reach Class 2500 and meets the strict working conditions requirements in the petrochemical and air separation fields.
