Marketing InformationThis VKD valve has a socket end and a threaded end for connections to a piping run; It also features a PP body with EPDM seals to ensure reliable transportation of materials. The patented Dual Block system allows for the locking of union nuts in a preset position, assuring seal integrity under severe service conditions. A patented seat stop carrier, high quality stem and ball support system, integral mounting flange and bracketing, and a multifunctional locking handle (standard on sizes 2-1/2'''' to 4'''') set this valve apart from the rest.
