Description
The ball is installed from the top of the body. When the valve has malfunction on the pipeline and needs repairing, there is no need to disassemble the valve from the pipeline. Just remove its middle flange bolts and nuts, take off the bonnet and stem assembly from the body, and take out the ball and seat assembly. The ball and seat can be repaired on the line. The50TSeriesvalveismainlyusedon Process control pipelines in petroleum or chemical industry. Its use and maintenance are convenient. The angle between the seat andbodyis10°. The seat can realize self-locking. On the pipeline, when the seat receives relatively high pressure, the seat will not make any movement. Therefore, the valve of this structure has the features of gate valves and advantages of ball valves.

Stem sealing
·The graphite packing formed through mold pressure serves as the dynamic load seal to ensure reliable sealing and long service life.
·The high strength stem can effectively transfer torque and ensure reliable on-off of the valve.
·The stem and ball fit tightly with each other, reducing hysteresis and dead band with excellent control performance.
Seat sealing
·The seal conforms to the requirements in GB/T13927 Class D or ANSI/FCI70-2CLASSVI.
·Reliable double-way sealing
·Excellent sealing performance in low pressure service conditions.
