Line butterfly valve in the high-performance anti-corrosion series of special role

Butterfly valve in the high-performance anti-corrosion series of special role 1, the use of two-piece stemless pin connection, simple and compact structure, maintenance and disassembly is extremely easy (removable disassembly); plate with automatic alignment (up and down, left and right) Achieved a small disc and seat interference with. 2, Tongue groove seat, to ensure accurate connection between the valve body, seat, disc, while the seat can be easily replaced. 3, using the world's most advanced spherical seal, seal more reliable. Because it is a spherical seal, the valve is smooth over the opening and closing, so reduce the friction and reduce the torque, you can choose a low-power drive, thereby Reducing the cost of the user. At the same time improve the life of the valve seat (3-4 times the normal center line valve). 4, seat flange sealing surface with wide-brimmed, large arc structure, so that the valve can be fully fitted or welded flange connection requirements, suitable for connection with any standard flange. 5, the valve stem axial positioning device, the use of two pads plus a pair of open-loop and spring clamp ring structure. This can also effectively prevent the stem from being inadvertently disassembled, while carrying a certain axial force, to prevent stem weight transfer to the butterfly plate. 6, stem seals from two-way seal, that is, to prevent the intrusion of foreign substances, while preventing media outflow. 7, sleeve from supporting the role of stem, but also reduce the opening and closing torque. There are currently two types of bushings available to the user, namely: Lubrication of bronze, Teflon. 8, due to the valve body itself instead of the ordinary seat backrest, an increase of the overall strength of the valve, so that it can reach the ordinary midline butterfly valve 20 kg nominal pressure can not be achieved.
