Category : Electric butterfly valve
Product Name : Wafer Electric Butterfly Valve
Product introduction:
Wafer electric butterfly control valve supports non-pin structure to effectively avoid the pin break off in a long- term operation as a modulation device to control and cut off the various industrial medium of water and oil to realize temperature pressure and flow control.
This valve is suited to the pipeline and container of non corrosive gas liquid semi-liquid and solid powder and applied in the industrial fields of petroleum chemical food medicine textile papermaking power shipwater and drainage smelting energy and so on.
