The products are summed up:
Flexible butterfly valve is it compensate pipeline expand with heat and contract with cold the convenient function loaded and unload automatically to have, use it under 425 degrees Centigrade in temperature, petroleum under 1.6MPa of nominal pressure, chemical industry , electricity , papermaking , for draining off water and urban constructioning ,etc. regulate the flow and the best device of the disconnected fluid in year at the industry pipeline. |
Characteristic of the products:
1, the structure is unique , the design is flexible , light, save effort , open and close it rapidly.
2, flexible butterfly valve can compensate difference in temperature of the pipeline contract the function expanding with heat and contract with cold that produce not merely, can change and provide convenience in order to maintain valve installation in the sea.
3, the sealed position is changed adjustably, the sealing property is reliable . |
