The Control Valve Selector Spool regulates the flow and pressure of hydraulic fluid within the transmission system and is used to control the movement of hydraulic fluid through corresponding passages and channels. By adjusting the position of the spool, operators can modulate the differential speed and pressure, thereby controlling the performance of the transmission system.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 Selector Spool facilitates smooth gear shifting and torque distribution, ensuring optimal power delivery to different components of the heavy machine. Simultaneously, the Pressure Control Valve Selector Spool regulates hydraulic pressure levels to prevent system damage, leaks, or inefficiencies.
