Features:

1.  The  disc  and  shaft  are  connected  without  pin  to  reduce  the  leakage 

between  them  and  achieve  on-site  replacement.  It  also  can  achieve 

optimal fit and open torque transmission by using O-ring sealing on the 

shaft.

2.  With polishing and precision machining on the sealing surface of disc, it 

can  achieve  a  completely  concentric  sealing,  lower  the  opening  and 

closing  torque,  extend  the  service  life  and  reach  bubble-tight  grade 

sealing. Streamlined design can minimize pressure loss.

3.  The seat is equipped with backrest, and the torque is stable. Customers 

can choose  the  rubber  and PTFE  in  different kinds  of materials. The 

outer edge of the rubber can lengthen the face to face of the body to 

replace  the  flange  gasket.  The  integrally  molded  O-ring  is  set  in  the 

shaft hole for sealing.

4.  The seat has no skeleton. The unique swallowtail design allows the 

seat  to  fit  the  body  completely,  effectively  squeeze  the  seat 

deformation  force  and  act  on  the  body  instead  of  shaft  to  avoid 

torque rising. The waterline design on the end face of the seat can 

play a better sealing performance during working process.

5.  Double semi-shaft design can ensure larger  flow rate per minute, 

and work for a long time without breakdown.

6.  Good economic benefit due to its simple structure, easy operation 

and strong repeated usability of the removal parts.
