Jacketed Ball Valve
Comprehensive range of jacketed ball valve for industrial applications across Africa. International standards compliant.
African Valve supplies jacketed ball valves in Egypt for applications where the process fluid needs to stay warm during operation. The valve has a jacket around the body through which steam, hot oil or another suitable heating medium can circulate. This helps keep the fluid moving and reduces the chance of it becoming too thick or solid inside the valve.
These valves are commonly used for bitumen, asphalt, molten sulphur, coal tar, pitch, resins, polymers, waxes, heavy oils and other temperature-sensitive fluids. Depending on the service, the valve can be supplied with a full or partial jacket, different seat materials and either manual or actuated operation.
How It Works
A jacketed ball valve works in the same basic way as a standard ball valve. The ball turns through 90° to open or close the flow. With the bore of the ball in line with the pipe, the valve is open. Turning the ball across the flow path shuts the valve.
The difference is the heating jacket around the valve body. Heating fluid passes through this jacket and transfers heat to the valve and process area. This is useful for materials that can harden, crystallize or become difficult to pump when their temperature drops.

Materials
Depending on the service, valve bodies can be manufactured from ASTM A216 WCB carbon steel or ASTM A351 CF8, CF8M, CF3 and CF3M stainless steel. Ball and stem materials may include SS304, SS316, SS410 and 17-4PH. Seat and packing materials are selected based on the operating temperature and the fluid being handled. The heating jacket can be supplied in carbon steel or stainless steel.
