CHEMLINE Valves Offers a range of Fully Jacketed Ball Valves. The Jacket covers the body from one flange to the other flange. The body is modified by adding over size flanges. As example : 2” x 3” Jacketed Ball Valve has nominal bore of 2” (Dn80). It allows enough space for bolting clearance.

The Jackets assure consistent Valve Heating or Cooling of the process media to prevent crystallization (solidification) or seizing of flow media and maintains the temperature of media. This applies specially to media like bitumen and liquid sulfur. In addition, the efficient flow of media is ensured through the elimination of pockets.

CHEMLINE Valve testing every jacketed valve again after the jackets have been welded (fabricated) to the body. Jacket Hydraulic & Air Test is Carried out at 6.0Kg./Cm2.
