Products Description
Engineered as a cost-effective alternative to solid bronze discs, our Bimetallic Hydraulic Motor Valve Plate bonds a CuPb10Sn10 lead-bronze friction layer to a heavy carbon steel backbone to control fluid distribution under continuous cyclic loading. We supply this high-rigidity Bimetallic Hydraulic Motor Valve Plate for medium-to-high pressure vane and piston motors driving industrial winches, injection mold units, and central factory hydraulic stations. By leveraging the rigid steel back to eliminate face deflection under high loads, our Bimetallic Hydraulic Motor Valve Plate reduces raw copper consumption by over 60% while maintaining quiet running and reliable volumetric performance.
Application Scenarios
- Port face distribution in medium-to-high pressure industrial vane and piston motors.
- Hydraulic drive systems in injection mold clamp units, machine tool tables, and winches.
- Motor core overhaul, remanufacturing, and preventative maintenance replacement.

FAQ
Q: How does this bimetallic plate compare to solid bronze valve plates?
A: The structural steel back prevents high-pressure warping while using 60% less copper, delivering identical anti-friction performance at a significantly lower unit cost.
Q: What payment terms and currencies do you support?
A: We accept USD settlements under EXW (preferred) or FOB terms, with 50% deposit before production and 50% balance before factory dispatch.
