Nine Major Features of Pneumatic Butterfly Valve
1. Small and lightweight, easy to disassemble and repair. Installable in any position.
2. The structure is simple and compact. The operating torque is small. Quick 90-degree rotary opening.
3. The flow characteristics is nearly a straight line. The regulating performance is good.
4. The connection between sanitary butterfly valve plate and stem is without pin, overcoming the possible internal leakage points.
5. According to user requirements, butterfly plate can be sprayed with coatings such as nylon or poly-tetrafluoroethane.
6. This kind of valve can be designed into flange connection and clamp connection.
7. It can be actuated manually, electrically or pneumatically.
8. The sealing can be replaced. And the sealing is so reliable that two-way sealing can be achieved.
9. The outer sphere of the butterfly plate uses spherical shape, improving the sealing performance and extending the service life of the valve. Zero leakage can still be maintained when opening and closing the valve under pressure for more than 50000 times.
