- Flowchem make jacketed ball valves are used for special applications. The jacket covers the body from one flange to the other flange. The body is modified by adding oversize flanges. As an example: 4" x 6" jacketed ball valve has the nominal bore of 4" (dn 100) and the flange size is 6"(dn 150). It allows enough space for bolting clearance.
- The jackets assure consistent valve heating or cooling of the process media to prevent crystallization or seizing of flow media. The jacketed ball valve (heating jacket ball valve) with very well design to help the high temperature steam or oil flow over the valve ball & body parts to keep the media liquid. This applies especially to media like bitumen and liquid sulfur. In addition, the efficient flow of media is ensured through the elimination of pockets. In jacketed ball valves, steam can be used as a carrier for heating media.
