Products Description
Delivering an economical balance of high structural rigidity and friction resistance, our hydraulic pump valve plate features a CuPb10Sn10 lead-bronze layer sintered to a heavy carbon steel base. We supply this versatile hydraulic pump valve plate for medium-to-high pressure vane and piston pumps installed across industrial central power packs, metal presses, and machine tool clamping circuits. Compared to solid bronze alternatives, our hydraulic pump valve plate reduces raw material costs by over 60% while providing flat, non-deforming port sealing that maintains quiet operation and long service intervals.
Application Scenarios
- Valve port sealing in medium-to-high pressure industrial vane and piston pumps.
- Hydraulic power packs in metal stamping presses, CNC tooling, and factory machinery.
- Routine pump cartridge replacement and remanufacturing for industrial maintenance.

FAQ
Q: Why choose a bimetallic valve plate over a solid bronze plate?
A: The steel backing prevents pressure-induced flexing while using 60% less copper, yielding equivalent wear performance at a significantly lower purchase cost.
Q: What are the commercial payment terms for volume production?
A: We require a 50% deposit to commence manufacturing, with the remaining 50% balance cleared prior to factory dispatch.
