Usage
This product is especially suitable for steel industry, aluminum industry, fiber, tiny solid particles, pulp, coal ash, petroleum gas and other media, can be customized according to different needs.

Features
The valve hemisphere with bimetallic, parent material on the surfacing of different alloys, the valve seat is also made accordingly surfacing by a special treatment, the sealing surface combination of anticorrosion, wear-resistant, high-strength and other types to meet the needs of different occasions.
Tight sealing, transportation of harmful gases up to zero leakage.
The spool of the sealing vice has a compensating amount, when the valve is worn out, it can be reliably sealed by turning a little when it is closed, which prolongs the service life.
