Product Description
The main structural features are:
1. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.
2. Sealing surface surfacing cobalt-based hard alloy, wear-resistant, corrosion-resistant, anti-scratch performance, long service life.
3. Built-in pin shaft structure, reduce the leakage point, the use of reliable.
4. When the pressure ≥ 16.0MPa,Class 1500, the valve cavity using self-sealing structure, the higher the medium pressure, the better the sealing performance.
5. The material, flange and butt welding end size of the parts can be reasonably selected according to the actual working conditions or user requirements to meet the needs of various working conditions.
