The Control Valve Differential Spool is a cylindrical-shaped valve that consists of a hollow center and multiple ports on its outer surface. These ports are strategically positioned to facilitate the desired flow and pressure control functions. The valve operates by sliding within a housing or body, which contains the necessary channels and passages for fluid flow.Attributes:• Hardened to Rockwell hardness of 30N 73 minimum, which determines it's resistant to deformation and wear• Withstands a wide temperature range, allowing it to function reliably even under extreme temperature conditionsApplications:The Control Valve Differential Spool controls the direction of fluid flow and regulates the pressure in a hydraulic unit. It achieves this by selectively directing the flow of hydraulic fluid through different channels and passages, as well as adjusting the size and shape of the flow passages to control the pressure levels.
