Products Description
Engineered to deliver long-term sealing stability in fluid systems with moderate filtration, our Wear Resistant Bimetal Valve Plate combines a structural carbon steel back with a wear-resistant high-lead bronze layer achieving ≥160 MPa shear bonding strength. We build this durable Wear Resistant Bimetal Valve Plate for medium-to-high pressure pumps and motors running continuously in metallurgical machinery, plastics plants, and mobile earthmoving machinery operating with NAS Grade 8–10 fluid cleanliness. Thanks to minimal structural flexure under high hydraulic loads, our Wear Resistant Bimetal Valve Plate resists thermal seizure and keeps continuous operating wear below 0.01 mm per 1,000 hours, significantly extending equipment overhaul intervals.
Application Scenarios
- Wear-resistant valve porting in medium-to-high pressure hydraulic pumps and motors.
- Continuous hydraulic operations in metallurgical mills, plastics machinery, and mining.
- Field maintenance and rebuild of outdoor hydraulic systems operating in dusty environments.

FAQ
Q: How does this valve plate perform when hydraulic oil contains particulates?
A: The high-lead bronze matrix absorbs micro-contaminants without scoring, while the steel back prevents pressure-induced flexing that could otherwise accelerate abrasive wear.
Q: What is your standard production tracking workflow for overseas buyers?
A: We provide regular photographic and video milestones across key stages-from furnace sintering to CNC double-face grinding and final CMM reporting.
