1. Achieves Precision Sealing for Zero Leakage

Lapping creates perfectly matched, ultra-smooth contact surfaces between the ball and seat, eliminating micro-irregularities and ensuring complete shutoff—especially crucial in metal-to-metal sealing applications.

2. Enhances Reliability in Extreme Conditions

Whether in high-pressure, cryogenic, or high-temperature environments, lapped surfaces maintain seal integrity, preventing fluid bypass even under thermal stress or extreme loads.

3. Extends Valve Service Life

Precisely lapped components reduce wear, galling, and surface fatigue, contributing to longer operational cycles and sustained zero-leakage performance.

4. Reduces Maintenance and Operational Costs

High-integrity sealing lowers the risk of leakage-related failures, minimizing unplanned shutdowns and reducing the frequency and cost of maintenance.

Teamco offers three premium coating materials, HVOF Tungsten Carbide, HVOF Chrome Carbide and HVOF Stellite, each designed to meet the specific demands of customer's applications. Choosing the right material for an HVOF coating is crucial for ensuring the coating meets the performance and durability requirements of the specific application. For a valve metal parts supplier committed to zero-leakage performance, ball & seat lapping is not optional—it's essential. It transforms precision-machined components into reliable, leak-proof sealing pairs. By incorporating this step into the production process, we ensure compliance with the world’s most stringent performance standards.
