Wafer type connection with minimal space occupation. The valve body does not have an independent flange and is directly clamped between two pipeline flanges using double headed bolts. Its axial length is only 1/2~1/3 of that of a flange butterfly valve, and its radial size is compact, reducing weight by 30%~60%. It is particularly suitable for narrow installation environments such as dense pipelines, equipment rooms, and underground pipelines, while reducing labor/equipment costs for handling and installation.
The eccentric butterfly valve’s hydraulic drive + adjustable stroke provides precise control of medium flow and pressure, offering stable throttling for fine working conditions.
The control box can set fast and slow closing or segmented closing, eliminating water hammer impact to protect pipelines, pumps, and equipment.
The eccentric structure opens and disengages immediately, minimizing friction on the sealing surface, resisting cavitation, and ensuring a long service life.
Standard export wooden case packaging ensures safe transit for all international shipments.
The adjusted hydraulic eccentric butterfly valves are widely used for working conditions with large caliber, medium-high pressure, and the need to eliminate water hammer impacts.
