Product Description
High Performance Flanged PTFE Lined Butterfly Valves


A butterfly valve consists of body, stem, disc, actuator (manual actuator, worm-gear actuator, aerodynamic actuator or electric actuator), and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.

1. Simple and compact construction. Small in size and light in weight. Easy transportation, installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque, energy saving.
3. Excellent sealing performance with ZERO leakage. Long service life.
4. Wide selection of materials, applicable for various media...
5. Flow curve tending to straight line. Excellent regulation performance.
