RU Description
The Sun Hydraulics Check Valve is an important part of the cartridge valve product line, mainly used for one-way flow control of hydraulic systems, allowing fluid to pass in one direction and preventing reverse flow, ensuring system safety and efficiency. Based on Sun's standardized threaded cartridge valve technology, ISO 7368 cavity compliance can be integrated directly into the valve block to reduce the risk of pipeline connection and leakage.
Features
The Sun Hydraulics Check Valve allows only one-way flow of fluids and automatically locks in reverse to prevent backflow or loss of system pressure. Wide operating pressure range, supported by typical models, up to 350 bar. The spool design is lightweight, ensuring quick opening and closing, reducing pressure fluctuations and shocks. Some models have opening pressures as low as 0.2 bar, reducing system energy loss.
Applications
The Sun Hydraulics Check Valve can be used in:
Construction machinery: used for excavators and crane hydraulic cylinder locking circuits to prevent uncontrolled load drops.
Industrial hydraulic system: pump outlet protection to avoid damage to the pump body due to fluid backflow during shutdown.
Energy Equipment: Wind turbine hydraulic pitch system maintains pressure to prevent accidental reset of the blades.
Mobile equipment: One-way pressure maintenance of hydraulic outriggers of aerial work platforms to ensure stability.
