iron butterfly valve

The DN250 wafer butterfly valve have small size and light weight. Easy instllation and mintenance. Itcan be mounted wherever nedded. The NBR seat butterfly valve siple and compact construction, small torque when open and close,quick go degrees on-off operation. This kind of butterfly valve is energy saving and flow curve tending to straight line. Excellent regulation performance and long service life. Standing the test of tens of thousands openingclosing operations.

1. Small and light, easy to disassemble and repair, and can be installed in any position. 2. The structure is simple and compact, the operation torque is small, and the 90 ° rotary opening is quick. 3. The flow characteristics tend to be straight line and the regulation performance is good. 4. The connection between the butterfly plate and the valve stem adopts the structure without pin, which overcomes the possible internal leakage point. 5. The outer circle of butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve, and keeps zero leakage after more than 50000 times of opening and closing under pressure. 6. The sealing element can be replaced, and the sealing is reliable to achieve bidirectional sealing. 7. Butterfly plate can be sprayed with coating according to user's requirements, such as nylon or PTFE. 8. The valve can be designed as flange connection and clamp connection
