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.

Application range: Suitable for use in pipeline systems in industries such as water supply, petrochemicals, metallurgy, mining, textiles, energy, papermaking, food, and steel, for switching the flow direction of the medium, as well as for splitting or mixing the medium flow.
The slow-closing check valve opens and closes the valve disc automatically due to the flow of the medium, and is a type of automatic valve used to prevent the backflow of the medium. It is mainly used to prevent backflow of the medium, prevent the reverse rotation of pumps and drive electric motors, and release the medium in containers. The check valve can also be used in pipelines that supply supplementary pressure to auxiliary systems where the pressure may rise above the system pressure.
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
Expanding Slab Gate Valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.
