- 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
- 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
- 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
- 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
- Double semi-shaft design can ensure larger flow rate per minute, and work for a long time without breakdown
- Good economic benefit due to its simple structure, easy to operate and strong repeated usability of the removal parts
