Characteristics
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.

Advantages
1.Accurate regulation and stepless flow control:
The eccentric butterfly valve’s hydraulic drive+adjustable stroke, precise control of medium flow/pressure, stable throttling and stabilization, suitable for fine working conditions.
2.Waterproof hammer and slow closing protective pipe network:
The control box can set fast and slow closing, segmented closing, flexible opening and closing, eliminate water hammer impact, and protect pipelines, pumps, and equipment.
3.Small opening and closing torque, wear-resistant and durable:
Eccentric structure (conventional combination) opens and disengages immediately, with low friction on the sealing surface, resistance to cavitation and impurities, and long service life.

Packing
Standard export wooden case packaging

Application Scenarios
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.
