The gate valve has a small fluid resistance, and the internal medium channel of the valve body is directly connected. The medium does not change
its flow direction when flowing through the gate valve. The torque required for opening and closing is small, the body structure is simple, the
manufacturing process is better, the sealing performance is good, and the corrosion of the dense cover when the full opening is less. The scope of
applications is wide. Because the phenomenon of the long water hammer is not easy to occur. The medium can flow in any direction on both sides
and easy to install.
Application Scenario: The non-rising stem gate valve is generally used in strict requirements on the height of the valve, but the use conditions are more harsh. For example, a high -temperature and high pressure working medium, toxic and harmful risk liquids require closure to ensure long-term
sealing and leakage. Under normal circumstances, the requirements for use requirements are reliable. Such as the application of power industry, petroleum
refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry and other fields.

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.
Side Entry Cryogenic Trunnion Mounted Ball Valve and extended valve cap ball valves will bring you huge profits in the field of low-temperature LNG services. Use temperature range-196°C~+150°C, with an extended valve cover design.
The Concentric butterfly valve is an industrial valve used for the on-off and flow control of pipeline systems. It is widely applied in fields such as petroleum, chemical industry, metallurgy, and hydropower. Its core structural feature is that the axis of the valve stem, the center of the butterfly plate, and the center of the body are on the same axis, featuring simple manufacturing and balanced opening and closing torque. By selecting different materials for the valve plate, valve stem, and sealing seat, it can be adapted to various different working environments, such as desulfurization, vacuum, and seawater desalination systems.
