I. Overview of Hydraulic Control Valve
Hydraulic automatic valves are suitable for centrifugal pump outlets, featuring functions such as flow control, non-return, soft start under light load, water hammer elimination, and flow regulation, effectively safeguarding the pump and pipeline equipment. The valve opening can be observed on-site and has a remote digital display. Additionally, it can output a 4-20mA DC current for centralized computer control.
Section II: Technical Features of Hydraulic Control Valves
Low resistance: Utilizes directional valve control technology; high valve plate opening with low resistance, resistance coefficient 0.3-1.1.
Compact size: The valve body features a butterfly structure, with a volume only 1/3 to 1/5 of the same diameter multi-functional hydraulic control valve.
Lightweight: Only 1/3 to 1/5 the weight of a multi-functional hydraulic control valve.
Long lifespan: Utilizes inclined sealing edges with automatic compensation for sealing surface wear, significantly extending service life.
Automatic Control: Valves and pumps are linked through the pipeline medium, with pump-valve联动, no manual intervention required; pump on, valve open; pump off, valve closed.
Energy-saving and consumption reduction: Driven by medium pressure without external power source, achieving energy-saving and consumption reduction.
Sealed well: Utilizing a combination of soft and hard dual-sealing technology, effectively resolves the sealing difficulties of large-diameter valves, ensuring "0" leakage for the long term.
Easy Opening and Closing: The large valve plate features an off-center structure with low friction torque, allowing for effortless opening and closing.
Easy Maintenance: Control system components are all outside the valve body, making adjustments simple, repairs convenient, and available for online inspection.
