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.

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.
Compared with other valve products, High Temperature and High Pressure Slab Gate Valve is characterized by high temperature and high pressure. Among them, grooved flange is designed as a unique self-tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The high-temperature and high-pressure gate valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the sealing surface of the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
Forged steel globe valve is a high-performance fluid control equipment, manufactured with high-quality forged steel materials and precision, integrating throttling and shut-off functions. Specially designed for high-pressure and high-temperature working conditions, it has the characteristics of compact structure, reliable sealing, and long service life, and is widely used in harsh working conditions in industries such as petroleum, chemical, and power.
