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.
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. 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, and effectively avoid medium waste.
3. Strong driving force and stable operation with no impact or noise. Combined with a double-eccentric or triple-eccentric design, it reduces maintenance frequency and costs by significantly extending the service life of the sealing surface.
Standard export wooden case packaging ensures the safety of the valve during long-distance transportation and prevents any mechanical damage.
The adjusted hydraulic eccentric butterfly valves are widely applicable to power stations, water conservancy, pump stations, petrochemical and other industrial fields.
