A Spool Kit is an integral part of hydraulic systems with steering priority valves. It is designed to maintain the integrity of the spool by preventing foreign contaminants from entering the valve and potentially causing damage or malfunctions. The kit comprises a protective screen or filter element. The kit's screen or filter element acts as a barrier to prevent foreign particles, such as dirt, debris, or other contaminants, from entering the steering priority valve. This safeguard is required to maintain the proper functioning of the spool in the steering priority valve.Attributes:• Screen is designed to capture and block contaminants.• Maintain the proper functioning of the priority valve.Applications: A Spool Kit is used to replace the screen in the steering priority valve to block contaminants before they can enter the valve.
