Features

three ball valves have two seats and four seat sealing structure, the valve core hole with L type and T type two kinds of structures, the use of control spool rotation, change the connection state of valve channel and mouth of the pipeline, fiber granular fluid. Sealing requirements are more stringent for the occasion, Fluid resistance, ball valves are all in one fluid path of least resistance, even if reduced diameter valve, the fluid resistance is quite small. |||
Stem thrust bearing to reduce friction torque, can balance the long-term operation of a flexible stem. |||
Seat sealing performance, the use of seals made of PTFE and other materials, the structure is easy to seal, and the ball valve sealing capability with additional media pressure increases. |||
Stem seal reliable, because the stem only for rotary motion without doing lifting exercise, easy to damage the valve stem packing and sealing capability with the addition increases the pressure medium. |||
Since PTFE and other materials have good self-lubricating, low friction loss and sphere, to help the life of the big ball. |||
Bottoms type stem and stem head convex order to prevent the stem spray, such as stem seal damage caused by fire, convex order metal contact and the body can be formed to ensure the valve stem seals. |||
Anti-static function: Set between spring ball, stem, body, switching process can generate static electricity export.
