What Does the Valve Plate Do in a Hydraulic Pump?
In excavator hydraulic systems, the valve plate ensures proper oil direction between the pump cylinder and pistons. A worn plate leads to leakage, reduced swing efficiency, and overheating. YNF’s PCR-5B-30A valve plate offers high surface precision, corrosion resistance, and optimized pressure control for tough working environments.
