The Pilot Operated Relief Valve is used to protect against excessive pressure that could damage system components. It operates using a pilot mechanism, which allows for proper control over the valve's opening and closing. When the system pressure exceeds the valve's preset limit, the pilot valve activates, causing the main valve to open and release excess fluid back into the reservoir or another low-pressure area. This action reduces the system pressure, maintaining it within safe operating limits.Attributes:• Provides adequate flow capacity to handle required discharge.• Allows rapid opening and closing for effective pressure protection.• Withstands pressure surges without failure.Applications: The Pilot Operated Relief Valve is located within the joystick control valve assembly, to monitor and regulate the hydraulic pressure that is applied to hydraulic functions controlled by the joystick.
