Customization Services
Customized carbide valve head solutions. Valve heads are designed and manufactured to meet specific customer needs and operating conditions for specific applications. The dimensional specifications of carbide valve heads will vary depending on the type of valve and customer requirements, common specifications include diameter, height, and thread size.
Performance Parameters
- Hardness: May reach HRA85 or above, which ensures its abrasion resistance under harsh working conditions.
- Résistance à l'usure: High hardness enables the valve head to maintain a low wear rate in long-term use.
- Corrosion resistance: The outer surface is usually treated with anti-corrosion treatment to enhance its corrosion resistance.
- Heat resistance: Can maintain its stability at high temperatures, without significant performance degradation.
