The Single Disc Check Valve adopts a low-inertia design, featuring fast response and adjustable closing time. The contact surface between the valve disc and the valve seat is specially hardened, ensuring excellent wear resistance. A spring-assisted closing option is provided to prevent backflow of the medium. The overall structure is compact, and the installation orientation is not restricted. The working pressure can reach Class 2500, with a temperature range of -196℃ to 550℃. It meets the requirements of international standards such as API 6D.

Application range: The check valve is generally used in the pipeline where the convection resistance requirement is not strict, that is, where the pressure loss is not considered. Such as high temperature and high pressure working media, toxic and harmful dangerous liquids, the closing parts are required to ensure long-term sealing and no leakage. In general, the conditions of use require reliable sealing performance. Such as power industry, petroleum refining, petrochemical, offshore oil, urban construction of water engineering, chemical industry and other fields of application.

The C-type wear-resistant ball valve is a valve designed specifically for harsh working conditions, characterized by its eccentric ball setting and "C" - shaped channel. This design cleverly utilizes the translational characteristics of the sphere during rotation, achieving a "wedging" effect with the valve seat, thereby significantly improving the sealing performance. In addition, its ingenious upper and lower support axis positioning structure not only ensures the stability of the sphere, but also avoids tilting, allowing the medium thrust to be evenly dispersed, thereby extending its service life. This design not only optimizes the sealing performance, but also reduces the opening and closing torque and improves the opening and closing efficiency. Widely used in industries such as coal chemical, petrochemical, offshore platforms, LNG, etc.
The structure adopts a short pattern, the valve gate is light in weight, and the pipe support frame can be saved. Diversified Drive Modes: Electric, gearbox, hydraulic and pneumaticcan be selected at will. High performance sealing combination packing: The combined packing sealing system isadopted to greatly improve its sealing performance.
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. The components of the self-operated pressure regulator and differential pressure regulator are interchangeable. If the control conditions change, the spring & diaphragm components can be easily replaced. The accuracy of the self-operated control valve surpasses that of similar products, and it also offers high stability. Diversified product series: self-operated pressure regulator, self-operated micro-pressure regulator, self-operated temperature regulator, self-operated flow regulator, self-operated nitrogen-sealing valve, and self-operated (combined) regulator...
