Electric low-temperature regulating valves are designed specifically for extreme low-temperature environments and are core control equipment in fields such as liquefied natural gas (LNG) and cryogenic chemicals. The valve is powered by an electric actuator and achieves remote precise control by receiving 4-20mA standard signals. With the help of an intelligent positioning system, the adjustment accuracy can reach ± 0.5%. The valve body is made of low-temperature resistant austenitic stainless steel (such as 304L, 316L) or nickel based alloy. After deep cryogenic treatment, it maintains excellent strength and toughness even in ultra-low temperature environments of -196 ℃; The sealing components are made of polytetrafluoroethylene (PTFE) or low-temperature rubber material to ensure zero leakage. The unique elongated valve stem design effectively blocks low-temperature transmission and prevents the actuator from freezing and failing; The double-layer packing box structure enhances the sealing performance and avoids the loss of cooling capacity. With the advantages of fast response, low energy consumption, and high reliability, electric low-temperature regulating valves are widely used in the gasification process of LNG receiving stations and liquid nitrogen transportation systems, providing stable guarantees for the flow and pressure regulation of low-temperature fluids, and assisting in safe production and efficient operation under extreme working conditions.

Pneumatic lined rubber butterfly valve is a star product in the field of industrial fluid control that combines efficiency and reliability. It is powered by compressed air and uses a pneumatic actuator to push the butterfly plate. With a rapid rotation of 90 °, it can accurately achieve valve opening and closing and flow regulation. It has a sensitive response and strong power, especially suitable for complex working conditions that require frequent start stop and quick switching of fluid on/off. ​ Its core advantage lies in the rubber lining covering the surface of the valve body and butterfly plate, commonly made of natural rubber, chloroprene rubber, nitrile rubber and other materials, which provide a strong protective barrier for the valve. These rubber liners not only effectively resist the erosion of medium concentration acid-base solutions and salt media, but also have good wear resistance and tear resistance. Even under the flushing of fluids containing particle impurities, they can maintain the integrity of the sealing surface and reduce the risk of leakage. Meanwhile, the high elasticity of rubber enables the butterfly valve to tightly adhere to the valve seat when closed, achieving zero leakage sealing and ensuring precise and stable fluid control. ​ In the municipal water supply and drainage system, pneumatic rubber lined butterfly valves can efficiently regulate the flow of urban water supply and sewage discharge; In the paper industry, when faced with pulp containing corrosive chemicals, it can operate stably to ensure smooth production processes; In the food and beverage industry, rubber liners that meet hygiene standards enable them to safely transport various liquid raw materials and meet food safety production requirements. During use, regularly checking the airtightness

Electric rubber lined butterfly valve is an important device for achieving precise fluid control in industrial pipeline systems. It is powered by an electric actuator and drives the butterfly plate to rotate by receiving electrical signals. Within the rotation range of 0 ° -90 °, it can easily open, close, and adjust the flow rate of the valve. It can quickly respond to control commands and meet the high degree of automation in industrial production needs. ​ The unique feature of this valve is that both the valve body and the butterfly plate surface are lined with rubber materials such as natural rubber, nitrile rubber, EPDM rubber, etc. These rubber liners act as sturdy protective shields, effectively resisting corrosion from weak acids, weak bases, salt solutions, and some organic solvents. They also have good wear resistance and flexibility, and can maintain the integrity of the sealing surface even under fluid erosion, reducing the risk of leakage. At the same time, the elastic properties of rubber materials enable butterfly valves to tightly adhere to the valve seat when closed, achieving zero leakage sealing and ensuring precise fluid control. ​ In water supply and drainage engineering, electric rubber lined butterfly valves can stably control the water flow of urban water supply and sewage treatment systems; In the food processing industry, rubber liners that meet hygiene standards can safely transport materials such as juices and sauces, ensuring food safety; On the light industry production line, facing corrosive process fluids, it can also maintain stable operation of the production process with excellent corrosion resistance and sealing performance. In daily use, regular inspection of the circuit and lubrication of the electric actuator, timely cleaning of impurities inside th

In industries such as chemical engineering, environmental protection, and dyeing, the pneumatic fluorine-lined control valve has emerged as a pivotal device in industrial fluid control, renowned for its exceptional corrosion resistance and precise adjustment capabilities. Constructed with a metal body and internally lined with fluoroplastics like polytetrafluoroethylene (PTFE), this specialized lining acts as a robust barrier, shielding the valve from the corrosive effects of strong acids, alkalis, and oxidizing agents. Even when exposed to highly aggressive media such as hydrochloric acid or hydrofluoric acid, the valve maintains stable mechanical and sealing properties, significantly extending its service life.

In industries with extremely high requirements for fluid control precision and corrosion resistance, such as petrochemicals, fine chemicals, and papermaking, the electric fluorine-lined ball valve has become a core component of industrial pipeline systems due to its outstanding performance. The valve uses a metal body as the base, with a dense fluoroplastic lining (such as polytetrafluoroethylene, PTFE) inside. This "protective armor" can not only withstand the erosion of highly corrosive media like sulfuric acid and aqua regia but also tolerate extreme temperatures ranging from -180°C to 260°C, ensuring the valve operates stably for a long time in harsh environments.

When Mr. Liang Guihua, Chairman of Cepai Group Co., Ltd., made the decision in 2019 to invest in a high-end automated production line for high-precision valve components—each weighing over several thousand kilograms with a minimum batch size of just over 10 pieces—he was met with almost universal opposition from all senior executives of the company and skepticism from peers in the industry. Comments abounded: "Doing automation for such small batches is just grandstanding," "With various types of valves, different specifications and sizes, and all kinds of special materials, how can automation be achieved?" "How to guarantee product quality?"... Now, three years later, this flexible production line, which integrates 6 high-end machining centers, stretches nearly 100 meters, and is hailed as the largest in the Asia-Pacific region for multi-variety, small-batch production, has been successfully put into operation. It has shattered all doubts with outstanding performance—doubling production efficiency and reducing production personnel by 40%—and has also become the "bedrock" of Cepai's Smart Dream Factory, laying a solid foundation for the company to rank among China's most sophisticated high-end valve manufacturers.

During the Mid-Autumn Festival and National Day holiday, the reporter visited Cepai Group Co., Ltd. Inside the factory, more than 80 assembly workers were working overtime at their respective workstations.
