Product Details
First, the structural characteristics
The manual worm gear blind valve is mainly composed of the left valve body, the right valve body, the screw rod pair, the flap, the seal ring, the lever, the worm gear and other components. The rigid base body and the support column form a rigid structure body. Rubber ring embedded in the flap, with high temperature, good sealing performance, easy replacement, long service life and so on.
