WIN-WIN Jacket Valves Series are mainly used in the pipelines of Chemical, Pharmacy & heavy oil-transportation industry.

The key advantage of WIN-WIN Jacket Valves  is that valves could be easily and quickly operated under the ambience temperature below zero celsius degree due to the inner jacket function under inlet connected with steam.

WIN-WIN Industry 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 oversize flanges. As example: 2" x 3" Jacketed Ball Valve has the nominal bore of 2" (DN 50) and the flange size is 3"(DN 80). 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.

Steam, can be used as carrier for heating media. Following quality assurance rules, every valve is tested again after the Jackets have been welded(Fabricated) to the body. Jacket Hydraulic & Air Test is carried out at 6.0 Kg./Cm2.

Generally standard Jacketed Ball Valves are delivered in carbon steel and different types of stainless steel materials. Other special materials are available upon special request.

WIN-WIN Jacketed P.T.F.E. seated Ball Valves gives Zero Leakage, Tight Shut-Off and Low Torque with easy smooth operation at temperature ranging from -200 C.to +220 Degree C. Electro-Polished, Buff Finish & Ultra clean valve also provided for Food & Pharmaceutical Industries on request.

WIN-WIN Ball Valves are generally supplied with manual hand lever or gear unit operated, depending on valve size. Dharmi Engineers also offering Ball Valveswith either Pneumatic or Electrical actuator operated for automation.


WIN-WIN Ball Valves are also available with different type of Seat, Seal & Packing material such as P.T.F.E. (Virgin) / Glass Filled P.T.F.E. / Carbon FilledP.T.F.E. / Graphite (Grafoil) / PEEK to suit special requirement of client.
