The valve is electric drive or worm drive, flange connection, implementation of JB/T 8527 standard, three eccentric butterfly valve is the butterfly plate rotation axis (valve stem axis) and the butterfly plate sealing surface of a deviation, the valve seat rotation axis and the valve body flow path axis formed an Angle. The valve is composed of valve body, butterfly plate, valve stem, butterfly plate seal ring, butterfly plate pressure ring, support, end cover and other parts
Electric or cochLEAR OPERATION to turn the STEM 90° and drive the disc 90° to open or close.
Because THE product is three eccentric structure, can produce a CAM effect in the opening and closing process, reduce the valve switching torque, reduce the wear between the seat and the butterfly plate, prolong the service life of the valve

1. The valve adopts three eccentric structure, with the tighter sealing function, the sealing performance is reliable.
2. Butterfly plate sealing ring adopts multi-layer plate combination of flexible graphite and stainless steel plate, medium corrosion resistance, erosion, maintenance free, long service life.
3. The sealing surface of the valve body is the body processing technology, resistant to medium corrosion and erosion, maintenance free, long service life.
4. High strength of butterfly plate, large flow area, small flow resistance.
5, the valve shaft is sealed with flexible graphite packing, the higher the medium pressure, the better the sealing. Wear of the packing can be compensated by continuing to compress the packing gland.
1. This product should be stored in a dry warehouse and is strictly prohibited to be stored in the open air.
2. The medium flow direction should be consistent with the arrow direction on the valve body when the valve is installed.
3. The pressure test should be carried out before installation, and it can be installed after passing the test.
4. The pipe and valve cavity should be cleaned before installation.
5. The product shall not be subject to large external force after installation.
6. The operating conditions shall meet the technical requirements in the performance specifications.
7. Set the valve bracket if necessary.
8. Long-term storage, regular maintenance.
9. Generally, it is not allowed to open the electrical box cover, motor and other sealed parts outdoors on rainy days. When opening the electrical box cover, the power supply must be cut off first
