456-7268: Control Relief Valve

Description:
The bucket stick control relief valve is responsible for regulating the pressure of hydraulic fluid in the circuit, ensuring that it does not exceed safe levels. When the hydraulic pressure in the circuit exceeds the valve's preset limit, the valve opens and allows excess fluid to flow back to the hydraulic tank. This relieves pressure on the system and prevents damage to the hydraulic components, such as the cylinders and hoses.

Attributes:
• It must have a low leakage rate, which means that it should not allow hydraulic fluid to escape from the circuit when it is closed.
• It must be able to handle the flow of hydraulic fluid through the circuit, which is determined by the size of the valve orifice and the hydraulic system pressure.

Applications:
The bucket stick control relief valve allows the operator to control the digging, lifting, and grading capabilities of the Backhoe, which is useful for a wide range of construction and landscaping tasks. It is used in Cat 424B, 424B2, and 424B HD Backhoe Loaders.
