Overview:

Electric fluorine-butterfly regulator developed by jiangsu scene wheat automation instrument electric actuators and fluorine-butterfly butterfly valve, fluorine-butterfly plastic butterfly valve adopts the international popular soft lining process, in contact with the medium are lined 2 -- 3 mm thick of fluorine plastic (F46 or PFA), has a good anti-corrosion performance, rapid opening and closing, long service life, the advantages of small leakage.

Lining fluorine plastic butterfly valve with pneumatic piston actuator or electric actuator to meet the various requirements of automatic control and widely used in chemical, oil, metallurgical, pharmaceutical, power, and environmental protection and other industrial production process of on-site automatic adjustment, cut off, and remote control.

Fold the valve structure and composition

Soft lining butterfly valve small startup, shut down moment, has the very good switching performance;

Keep soft seat base is made up of rubber injection molding forming, contact with the medium of the lining by F46 (PFA) injection molding forming, into both the use of special process in the body, convenient maintenance, replacement seat.

Structure principle

Valve body cavity and the butterfly plate lining F46 (PFA), almost all chemical medium corrosion resistance, and can resist the penetration of fluorine ion; for a long time

Soft lining seat in the disc is closed, with the right amount of elastic deformation, ensures zero leakage of valve;

Butterfly plate and shaft for integrated manufacturing, using PFA between shaft bearing, both the use of shaft guide effect, but also has good lubrication;

Between disc and seat ring with a mechanical seal protection, no leakage between shaft;

Soft lining butterfly valve is a kind of flexible composite material, plus four fluorine rubber composite seat in valve is closed can produce certain elastic deformation, which ensures zero leakage reciprocating and excellent performance, and greatly prolong the service life of the butterfly valve.
