Product details

【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.
