DN50~1200 mm
Product description :
Electric butterfly valve is a perfect combination of electric actuator and valve of the title, the same need torque configured to conform to the international SIO5211 standard platform for mutual connection, plus or minus 5 degrees to achieve precision fine-tuning, and union.
Characteristic :
- The utility model adopts double eccentric structure, and has the sealing function of more and more close.
- The sealing materials of stainless steel and nitrile rubber oil resistant pairing, long service life.
- Butterfly plate adopts frame structure, high strength, large flow area, small flow resistance.
- The rubber sealing ring can be positioned on the valve body, and can also be arranged on the butterfly plate.
- The overall paint, can effectively prevent corrosion and as long as the replacement of the seal seat material can be used in different media.
- The utility model has the function of bidirectional sealing, and is not controlled by the flow direction of the medium, and is not affected by the space position. Can be installed in any direction.
- The utility model has the advantages of small size, light weight, reliable performance, simple matching and large flow capacity, and is especially suitable for the medium to be clean liquid and gas.
