220E

220E eccentric angular travel control valve spool metal or metal to PTFE seal with rotary ball valves, which combines the control characteristics of ball valves and butterfly valves into one, can be used as both a control valve and shut-off cut-off valve. V-shaped cut on the spool and the metal valve seat has a shear effect, suitable for controlling high viscosity, containing fibers, solid particles and slurry and other media. Structure of the paper industry pulp is particularly superior. Valve has an approximate equal to the ratio of flow characteristics, adjustable range, adjustable ratio of 100:1, but also has the function of regulating and positioning.
