D71F4 PTFE full lined butterfly valve
D71F4 PTFE full lined butterfly valve Product introduction
D71F4 PTFE full lined butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type D71F4 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.
D71F4 PTFE full lined butterfly valve feature:
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.
