Excavator Pump Parts Hydraulic Pump Repair Parts PSVD2-26E/27E Valve Plate for KYB Kayaba Excavator
Flow Distribution and Commutation: While the cylinder block revolves, each plunger chamber connects alternately to high‑pressure and low‑pressure oil ports automatically to achieve oil suction and delivery, eliminating the need for an independent directional valve.
Sealing and Isolation: It creates an oil‑film friction pair against the cylinder block end face, separating high and low pressure chambers to stop internal leakage.
Load Bearing: Endures hydraulic clamping force and lateral force from plungers, ranking among the three core friction pairs of pumps and motors.
Vibration and Noise Reduction: Transition sections and pressure relief grooves mitigate pressure spikes, flow pulsation and operational noise.
