Adjustable Hydraulic Cylinder Butterfly Valve - Double Eccentric Type by China Suppliers & Factory, DN200-DN3000
| Valve Type: | Eccentric butterfly valve | Structure: | Eccentric |
| Standard: | EN/DIN/API | Workmanship: | Investment casting |
| Sealing direction: | Single-directional | Sealing grade: | Zero leakage |
| Temperature: | -20°C | Operation: | Hydraulic control |
Characteristics
The oil cylinder control butterfly valve with eccentric structure design greatly reduces friction on the sealing surface during opening and closing, with the advantages of wear resistance, cavitation resistance and bidirectional zero leakage, significantly extending the service life of the valve. At the same time, it has strong hydraulic driving force, suitable for large-diameter and high differential pressure working conditions, and can easily realize opening and closing operations. It can also be connected to the PLC/DCS automatic control system, supporting remote linkage and local manual dual operation modes.
Advantages
1
The hydraulic control adjustable butterfly valve takes the hydraulic control system as the core, combined with a precise adjustment mechanism and an optimized disc design, which has multiple advantages of reliable control, flexible adaptation and high efficiency and energy saving.
2
The core advantages of hydraulic valve are concentrated in high adjustment accuracy and strong working condition adaptability. According to on-site process requirements, it can accurately adjust the medium flow and pressure, realize stepless adjustment from fully open to fully closed, adapt to the pipeline operation needs under different loads, and effectively avoid medium waste and system energy consumption loss.
3
The hydraulic butterfly valve adopts a hydraulic drive mode, with strong driving force and stable operation, no impact and no noise during opening and closing. Combined with a double-eccentric or triple-eccentric structure design, it greatly reduces the friction of the sealing surface, has the characteristics of wear resistance, cavitation resistance and bidirectional zero leakage, significantly extends the service life of the valve, and reduces the frequency and cost of later maintenance.
Packing
Standard export wooden case packaging
Application Scenarios
