【VQ947H / VQ977H electric V-type ball valve - Product Description】
Electric
V-ball valve with a cylindrical spring preloaded compensated movable
metal seat structure, sealing performance and reliable. Core and valve
seat will not produce jamming or detachment, long service life. The
V-shaped cutout on the core has a shear effect with the metal seat,
especially suitable for controlling medium with high viscosity, fiber,
solid particles and slurry. Paper pulp industry structure is
particularly superior. Valve flow capacity, pressure loss is small, and
the medium will not be deposited in the valve body cavity, the valve not
only has a similar ratio of flow characteristics, adjustable range, the
maximum adjustable ratio of 100: 1, but also with accurate Adjustment
and reliable positioning of the function.
