2 Way metal seated jacket ball valve manufacturer, factory and supplier in China. 2 Way metal seated jacket ball valve is suitable for the service temperature higher than 200 degree C. Jacketed ball valve, also known as insulated ball valve, is a special ball valve equipped with an enclosed jacket cavity outside the valve body. Heat medium such as steam, thermal oil or hot water can circulate inside the jacket to maintain constant temperature of the process medium inside the valve. 2 Way metal seated jacket ball valve is specially designed to solve transportation and shut-off problems of high-viscosity, easily solidified and crystallized media, 2 Way metal seated jacket ball valve is widely applied in petroleum, chemical, pharmaceutical, food, asphalt, resin and other process piping systems.

2 Way metal seated jacket ball valve Working Principle
A sealed heat exchange chamber is formed between the valve body and the outer jacket. Circulating steam, thermal oil or cooling water continuously heats, keeps warm or cools the internal medium to prevent solidification, crystallization and adhesion on the flow passage, ensuring smooth fluid flow and reliable valve operation. Meanwhile, it retains the inherent advantages of ball valves: quick opening & closing, low flow resistance and tight sealing performance.
2 Way metal seated jacket ball valve Structural Features
1.Integral welded jacket: Welded integrated structure without middle flange, minimizing leakage points, compact layout, light weight and stable pressure resistance. The full-coverage jacket ensures uniform heat exchange over the entire valve body.
2.Reliable sealing: Floating ball or trunnion ball design with bidirectional tight sealing, zero external leakage, suitable for severe working conditions.
3.Smooth flow channel: Full port and reduced port options available, extremely low flow resistance, less material accumulation and convenient pipeline cleaning.
4.Multiple actuation options: Manual, worm gear, pneumatic and electric actuators to meet automatic and remote control requirements.
5.Customizable materials: Carbon steel or stainless steel valve bodies; jackets and sealing materials are selected according to working temperature and medium corrosion resistance.
2 Way metal seated jacket ball valve Advantages
1.Stable temperature control: Uniform full-range heat exchange, avoiding local condensation and crystallization, greatly reducing valve blockage and production shutdown risks.
2.High energy efficiency: Higher heat utilization rate and more uniform heat transfer compared with traditional tracing heating, lowering energy consumption and maintenance cost.
3.Balanced comprehensive performance: Combines the fast switching and long service life of ball valves with temperature control function of jacket structure, realizing multi-purpose with one valve.
4.Strong adaptability for harsh media: Ideal for asphalt, paraffin wax, heavy oil, resin, sulfur, syrup and other high-viscosity easily-solidified fluids.
2 Way metal seated jacket ball valve Typical Application Fields
1.Petroleum & chemical industry: Conveying pipelines of heavy oil, asphalt, paraffin wax, resin and sulfur
2.Pharmaceutical & food industry: Constant-temperature delivery of syrup, chocolate, grease and colloidal materials
3.Chemical & metallurgical industry: Shut-off and regulation of high-viscosity liquids and easy-crystallization chemicals
4.Environmental protection & coal chemical industry: Constant temperature control for viscous waste liquid and slurry pipelines
