The rubber sealing form of pneumatic wafer butterfly valve is a kind of soft seal butterfly valve, with rubber lining plate.
It is easy to operate, with tight sealing performance, long service life, and good sealing performance. It can be used to quickly cut off or adjust the flow rate.
Suitable for situations requiring reliable seal and good regulation characteristics.The valve body adopts the split type, and the sealing of both ends of the valve shaft is controlled by the rotating base between the disc and the seat.
Ensure that the valve shaft does not come into contact with the fluid medium in the chamber. It is widely applicable to the transportation of liquids and gases in various types of industrial pipelines, but it is not suitable for some severely corrosive media such as sulfuric acid, phosphoric acid, chlorine, strong alkali, sewage and other corrosive media. . If you need anti-corrosion then the fluorine-plated butterfly valve is more appropriate.
Main features of rubber-lined pneumatic wafer butterfly valve
The design is novel, reasonable, unique structure, light weight, rapid opening and closing.
Small torque, easy operation, effortless dexterity.
It can be installed in any position and convenient for maintenance.
The seals can be replaced, the sealing performance is reliable and the two - way seal zero leakage.
The sealing material has the characteristics of aging resistance and long service life.
Rubber - lined pneumatic dual butterfly valve actuator.The actuator is pneumatic actuator, also called cylinder, with new series GT or AT type, double acting and single acting, gear transmission, safe and reliable.The large diameter valve adopts the series AW pneumatic actuator to pull fork type transmission, the structure is reasonable, the output torque is large, have double acting type and single acting type.
Gear type double piston, large output torque, small size.
The cylinder is made of light metal with beautiful appearance.Manual operating mechanisms can be mounted on the top and bottom.The rack-type connection adjusts the opening angle and the rated flow.
The actuator can be equipped with feedback indications and various accessories for automatic operation.
The ISO5211 standard connection facilitates the installation and replacement of the product.
Both ends of the adjustment screw can make the standard product in 0 ° -90 °, to ensure the valve synchronization accuracy.
