An Air Shutoff Control Valve Spring Shim Plate is a flat, circular part that can be inserted or placed between the valve spring and the valve cover to achieve a desired fit or alignment. It acts as a spacer, providing a precise space adjustment between these two components, ensuring optimal control and reliable operation of the air shut-off valve. By inserting the shim, the spring is positioned at the desired height within the retainer, ensuring consistent force and proper engagement of the spring.Attributes:• Withstands the dynamic forces and vibrations generated during machine operation• Handles high pressure without deforming or breakingApplications:An Air Shutoff Control Valve Spring Shim Plate is used in the hydraulic hammer to provide positional assistance for the spring of the air shut-off control valve and enables the adjustment of space between the spring and the cover. It helps to create a uniform and controlled compression of the spring.
