Description : We offer a range of FULL JACKETED BALL VALVES. The jacket covers the body from one flange to the other flange. The body is modified by adding oversize flanges. Example: a 3" x 4" jacketed valve has the nominal bore of 3" (DN 80) and the flange size is 4"(DN 100). This to allow 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. This applies especially to media like bitumen and liquid sulfur. In addition, the efficient flow of media is ensured through the elimination of pockets. 
Steam can be used as carrier for heating media. Following quality assurance rules, every valve is tested again after the jackets have been welded to the body. Jackets are rated for heat transfer media pressures up to 150 psi (10 bar) 
Standard, jacketed ball valves are delivered in carbon steel and a variety of stainless steel materials. Other special materials are available upon special request.
