Main Features
Pressure Seal Design: The bonnet adopts a pressure seal structure. As the system pressure increases, the sealing performance is correspondingly enhanced, effectively preventing medium leakage, which is particularly suitable for high-pressure environments.
Welded Butt-Weld Connection: The butt-weld end (BW) connection method enables the valve to closely integrate with the pipeline system, enhancing the integrity and tightness of the system. It also reduces the risk of leakage at the connection and improves the reliability of the system.
Carbon Steel WCB Material: The valve body is made of carbon steel WCB, which has good mechanical properties and corrosion resistance. It can maintain stable operation within a wide range of temperatures and pressures, with relatively low cost and high cost performance.
Flexible Wedge Structure: Equipped with a flexible wedge gate, it can automatically adjust the fit between the sealing surface and the valve seat, ensuring good sealing performance during valve opening and closing. At the same time, it reduces operating torque and extends the service life of the valve.
Non-Rising Stem: The non-rising stem design ensures that the stem does not rise during operation, saving space and facilitating installation and maintenance. It also avoids the risk of medium leakage caused by stem rising.
Multiple Operation Methods: It can be equipped with a manual gear operating mechanism, which is easy to operate. Suitable operation methods can be selected according to actual working conditions to meet the needs of different users.
