Purposes and Features:

1. Suitable for the BF stove top pressure equalizing system, use as furnace top equalizing relief valve.

2. Soft and hard seals through hard alloy and silicon rubber;,valve plate has a self-centering function, reliable seal.

3. Valve is sealed upon the action of medium pressure and hydraulic cylinder in the process of closing.

4. Valve disc can far from the brushing of the medium when the valve is opened.

5. Main material: quality carbon steel.
