FREE-VALVE’sWorm gear box operation Wafer Type High Performance Butterfly Valves assures reduced seat wear and bidirectional, zero leakage shut off throughout the full pressure range.Itis divided into hardto hardsealingorhard tosoft sealingwithtwo structuresaccording to sealing surface material of the disc and seat.Thebutterflyvalve can realize rotary under the condition of low torque bytheresilient-seateddesign,which means a longer service life ,so as to cost-effective of choosing actuator.

Features

1.The valveseatmaterialisdivided into metal seat and soft seat,which makes the valve suitable for liquid or gas service with many applications.

2. Theseatcan bereplacedby loosening the seat ring bolts, saving the cost of the valve.

3. Theresilient-seateddesign ensures minimal seat wear and double offset disc design provides excellent throttling capabilities ,it has characteristic ofsuper long usage life, frictionless closure etc.

4.Blowout proof shaft design and the application ofself lubricated bearings.

5.Preventingthe disc fromclosing underover/under travel byadjusting mechanical stopper.

6. Disc sealing surface adopts spherical edge design.

7. Bidirectional equal seal, zero leakage.

8. According to the requirements of medium conditions, overlaying or spray welding different sealing materials on the sealing surface of the valve disc, such as STL, tungsten carbide, Cr13.
