Q641F single acting pneumatic two-piece flange ball valve

Product Overview

The VQ640F/H/Y type single acting pneumatic flange V-shaped ball valve has a shearing action on the valve seat due to the V-shaped structure of the ball core. Therefore, it is applicable to the control of relevant process parameters in the suspended liquid media containing fibers or tiny solid particles in papermaking, chemical industry, metallurgy and other industrial enterprises, especially for the automatic regulation or cut-off control of slurry, white water, black liquor, white liquor and other suspended particles in the pulping and papermaking production process and the concentrated and turbid slurry fluid media.

Unique Advantages
