closed type goggle valve

The valve is a reliable isolation equipment in gas medium pipeline. It is suitable for gas, gas and powder transmission pipeline in metallurgy, chemical industry, machinery, energy and municipal engineering systems. The chain wheel type goggle valve manual driving device is mainly used on the manual goggle valve requiring long-distance operation, and is assembled and connected with other parts of the valve through the valve driving device; By pulling the hand zipper strip, the remote manual operation of the valve is realized, so that the use of the valve is more flexible and is not limited by power and air source.
