Контргайка винта клапана управления поршневым насосом, M8 Caterpillar 2580144

The Piston Pump Control Valve Screw Lock Nut manages retention of the relief valve adjustment screw within the piston pump control system. After the relief valve screw is set to a required control position, the lock nut is tightened to prevent unintended rotation caused by operational movement or pressure change within the hydraulic circuit. This locking action maintains the selected relief valve setting, so pressure regulation behavior remains unchanged during operation cycles. Attributes:• Prevents rotation of the control screw after adjustment.• Supports stable control response under flow change.• Maintains engagement with the threaded control interface.Applications: The Piston Pump Control Valve Screw Lock Nut is used on the piston pump control relief valve to lock the adjustment screw and maintain the selected pressure control setting during operation.
