During the opening and closing process, the friction between the valve petals and the cover surface is small and wear-resistant. The itinerary height is relatively small. Sensitive action, good sealing performance; Open and close quickly. The overall structure: simple and compact, beautiful shape, low cost for throttling compared to regulating valve. Long service life and high reliability.
Application Scenario: The throttle stop valve is generally used on the pipelines where the flow resistance requirements are not strict and the regulatory flow requirements are not high. For example, a high-temperature and high-pressure working medium, toxic and harmful dangerous liquids, the
closure of closure must ensure long-term sealing, leakage and inaccurate regulating flow. Such as the application of power industry, petroleum refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry and other fields.

Special type control valves are customized valve products designed by our company for complex working conditions (such as high temperature, high pressure, strong corrosion, high precision, and low-temperature control, etc.). They possess the ability to precisely regulate flow and pressure, and can meet the stringent requirements in industrial processes.
Y-Type Check Valveis a type of valve used to prevent fluid backflow, named after its Y-shaped valve body. It allows fluid to flow in one direction, and when the fluid flows in the opposite direction, the valve automatically closes to prevent backflow.
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
