Resilient-seated Butterfly Valves

Features:

1.    The disc and shaft are connected without pinto reduce the leakage between them and achieve on-site replacement. It also canachieve optimal fit and open torque transmission by using O-ring sealing on theshaft.

2.    With polishing and precision machining on thesealing surface of disc, it can achieve a completely concentric sealing, lowerthe opening and closing torque, extend the service life and reach bubble-tightgrade sealing. Streamlined design can minimize pressure loss.

3.    The seat is equipped with backrest, and thetorque is stable. Customers can choose the rubber and PTFE in different kindsof materials. The outer edge of the rubber can lengthen the face to face of thebody to replace the flange gasket. The integrally molded O-ring is set in theshaft hole for sealing.

4.    The seat has no skeleton. Theunique swallowtail design allows the seat to fit the body completely,effectively squeeze the seat deformation force and act on the body instead ofshaft to avoid torque rising. The waterline design on the end face of the seatcan play a better sealing performance during working process.

5.     Doublesemi-shaft design can ensure larger flow rate per minute, and work for a longtime without breakdown.

6.     Goodeconomic benefit due to its simple structure, easy operation and strongrepeated usability of the removal parts.
