Relief Spool for Transmission The relief spool is designed to regulate the pressure within the transmission system. It helps maintain pressure within a specific range by controlling the flow of hydraulic fluid or air. The relief spool typically consists of a valve or spool-like component that moves within a housing or manifold. The position of the spool determines the flow of fluid or air and controls the pressure within the system.Attributes:• Ensures reliable and safe operation.• Protection against hydraulic fluid leakage. Applications:A Relief Spool for transmission is used to provide precise control and reliable operation of hydraulic fluid to flow through different pathways.
