A Compression Spring is used in valves to provide a force that pushes the valve closed when it is not in use. The spring is compressed when the valve is open, and when the valve is released, the spring expands and pushes the valve back into its closed position. This helps to ensure that the valve is tightly sealed.Attributes:• Manufactured to precise specifications and are built for durability and reliability • Provides consistent force throughout the entire range of motion for smooth and controlled movement Applications:A Compression Spring is used in spool control valves to prevent any leaks into the hydraulic system.
