Polymer composite ball cocks
FULL BORE BALL COCKS FROM POLYMER COMPOSITE MATERIALS ТS 2249-006-34724672-2016
Designed for use in water treatment systems, at power engineering and housing and communal facilities, at food, chemical and oil industry enterprises, on tank trucks for transporting solutions and bulk solids.
The advantages of the ball cock are its capacity to provide fast flow shut-off and high reliability in operation. These qualities have determined the choice of valve type for realisation of the project from composite polymer materials.
The composite solution ensures low valve weight, high valve chemical resistance, excellent performance properties as well as a lifetime appearance of the shut-off unit. These qualities are determined by the features and advantages of composite polymer materials, which are increasingly overtaking metals in new designs of equipment and assemblies. For example, composites based on ultra-resistant plastics are used for ball manufacturing, providing high abrasion resistance, which makes the composite solution more attractive for use than the metal ball option, when combined with universal chemical tolerance. The non-metallic ball cock is the result of a synthesis of the best available technologies in the field of polymer and composite materials processing.
The developed composite ball cocks are designed for shutting off pipelines for pumping various media, including aggressive chemical, abrasive as well as oil and gas products. Besides universal chemical resistance of composites used for ball cocks production and high inertness of these materials make it possible to recommend this version of ball cocks for food and biological media.
