Self-acting Flow Control Valve 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.
*SO-25108 adopts the pilot-operated pilot valve technology, which results in less valve sealing compared to the double diaphragm head structure type of valves. It is more sensitive in operation (there is no sealing between the valve stem and the valve body), ensuring the accuracy of the designed value.
*SO-25108 is different from self-operated pressure reducing valves that adopt double diaphragm heads and have a valve core with a flat structure and fast-opening flow characteristics. The valve core of SO-25108 adopts a valve core with approximately equal percentage flow characteristics.
*SO-25108 is equipped with adjustable flow-limiting elements, which can adjust the flow capacity according to the difference between the design parameters and the actual working conditions. This compensates for the need to reduce the flow capacity of the valve in actual working conditions without the need to replace small-diameter valves, thus saving costs.
*SO-25108's soft valve seat enables the nitrogen-sealed valve to reach the set value and fully close, reducing the impact of valve leakage on nitrogen sealing and achieving the effect of saving nitrogen.
*SO-25108 has a simple structure, is convenient for installation and debugging, and has low maintenance costs.
*SO-25108 has a wide adjustment range, ranging from 14 to 720 mmH2O water column, and can be selected and adjusted in five grades.
*SO-25108 has a fast response speed and high regulation accuracy.
*SO-25108 can play a safety protection role in the nitrogen sealing system of storage tanks.

Application range: It is applicable to the automatic control systems in industrial production processes such as water supply, petrochemical, heating and cooling, energy, papermaking, food processing, and steel manufacturing, where there is no (or cannot be used) driving energy. It is particularly suitable for the automatic control system devices in the gas production and transportation or gas supply and transportation.
Designed specifically for deep cold medium working conditions such as LNG, liquid nitrogen, and liquid oxygen, it adopts special stainless steel or low-temperature alloy valve bodies. Through deep cold treatment, it ensures reliable sealing even in an extreme environment of -196℃. The innovative lateral maintenance port structure allows for quick replacement of the sealing components without disassembling the valve, significantly improving maintenance efficiency. The optimized double eccentric butterfly plate, combined with multi-level metal hard seals, achieves zero leakage and long service life under ultra-low temperature conditions. At the same time, it is equipped with a longened valve stem heat insulation structure, effectively blocking the conduction of cold energy.
The self-regulating control valve is an energy-saving control device that does not require external driving energy. It relies on the pressure or temperature of the medium being regulated as its power source, automatically adjusting according to set values based on changes in the medium. This valve integrates multiple functions of detection and control into one unit, forming an independent instrument control system. The self-operated control valve adopts a standard modular design. Our products are characterized by: standardization, serialization, and generalization. This achieves a high level of these three aspects.
RAYS PDS Ball Valve is designed for extreme conditions characterized by high temperatures, high pressures, and abrasive media. Manufactured from premium alloy steel and enhanced with advanced hardening techniques, it offers exceptional wear resistance for both the ball and the seat. The hard seal design ensures superior sealing performance in harsh environments. Additionally, the valve features a robust construction and is easy to operate and maintain, significantly reducing maintenance costs. It is an ideal choice for heavy industries such as petrochemicals, power generation, and mining.
