Precision HMS072 valve plate ensuring stable oil distribution and efficiency in hydraulic piston pumps.
OEM-quality HMS072 valve plate with precision oil-channel machining
Ensures efficient oil distribution and stable pump displacement
Heat-treated, wear-resistant surface for extended service life
High sealing accuracy reduces internal leakage and improves efficiency
Ideal for pump rebuild centers, hydraulic shops, and aftermarket distributors
The YNF17130 HMS072 Valve Plate is a critical core component within the HMS072 hydraulic piston pump, responsible for controlling the oil distribution between the cylinder block and pump housing. Manufactured with high-strength alloy steel and precision-machined oil passages, this valve plate maintains highly accurate sealing surfaces, reducing internal leakage and improving overall pump volumetric efficiency.
Its hardened, wear-resistant surface ensures stable performance under high pressure, continuous operation, and severe working environments commonly found in excavators, industrial machinery, and hydraulic systems. A worn or scuffed valve plate is one of the most common causes of low pump pressure, slow hydraulic response, and overheating. Replacing it with the YNF17130 restores pump efficiency, stabilizes performance, and extends the service life of the entire rotating group.
YNF Machinery offers consistent quality, reliable inventory, and competitive pricing, making it an excellent choice for hydraulic service centers and aftermarket distributors.
