A Hydraulic Check Valve, also known as a non-return or one-way valve, controls the flow of fluids within a system. Its purpose is to allow the flow of fluid in one direction while preventing backflow in the opposite direction. It consists of a ball that opens when fluid flows in the intended direction. Once the fluid tries to reverse its course, the valve promptly closes, preventing backflow, maintaining consistent pressure levels, and preventing contamination for optimal performance.

Attributes:
• Offers dependable performance for fluid control.
• Contributes to the smooth operation of components.
• Maintains consistent pressure levels and prevents contamination.

Applications:
A Hydraulic Check Valve is installed in the service arm cylinder and the access ladder cylinder to prevent backflow of hydraulic oil. It maintains the integrity and efficiency of hydraulic systems, preventing potential damage and enhancing overall safety.
