Steam jacketed ball valve

Steam jacketed ball valve introduction
Steam jacketed ball valve is also called thermal insulation jacket ball valve, The jacket covers the body from one flange to the other flange. Jacketed ball valve body is modified by adding oversize flanges. As example: 2" x 3" Steam 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 steam 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,hot oil 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 bar.
Steam Jacketed Ball Valves are produced in carbon steel and different types of stainless steel materials. Other special materials are available upon special request.
 PTFE soft seated steam jacketed Ball Valve gives Zero Leakage, Tight Shut-Off and Low Torque with easy smooth operation at temperature ranging from -20° C. to +220° C. metal seated steam jacketed ball valve is also can be produced for high temperature medium.
Steam Jacketed ball valve operation: thermal insulation jacket ball valve is generally supplied with manual hand lever or gear unit operated, depending on valve size. We also supply steam jacketed Ball Valves with either Pneumatic or Electrical actuator operated for automation.

Steam jacketed ball valve working principle
Steam jacketed ball valve is installed on the basis of the ball valve metal jacket, used to inject steam or other heat preservation, cold media, to ensure that the medium in the valve can work normally.Thermal insulation steam jacketed ball valve according to the different structure of the ball valve, there are integral thermal insulation steam jacketed ball valve, two-piece thermal insulation steam jacketed ball valve, sandwicd-type thermal insulation steam jacketed ball valve and other structural forms, thermal insulation steam jacketed ball valve has a good heat preservation and cooling characteristics, with the valve's pain diameter and pipe diameter consistent, steam jacketed ball valve also can effectively reduce the heat loss of medium in the pipeline.It is mainly used in petroleum, chemical industry, metallurgy, pharmaceutical, food and other systems to transport high viscosity medium that can solidify at room temperature.
 
Steam jacketed ball valve has good thermal insulation, cooling characteristics, in addition to reducing the diameter of the thermal insulation ball valve, the valve size and pipe diameter to, the medium flow in a straight line, small resistance, can effectively reduce the heat loss of the medium in the pipeline, therefore, easy to solidify, high viscosity of the liquid medium has excellent performance.Except the two-piece ball valve, the valve body adopts the integral jacket design, which can keep heat and keep cold more evenly.Weld the outer side of the jacket and body to the jacket joint with a maximum allowable steam or cold water pressure of 1MPa.
