Heating jackets are required where the process temperature must be maintained through the valve in order to keep the process media fluid. In particular, where there is potential for media to be trapped within a closed valve the heating jacket can be vital in maintaining the process temperature and preventing the trapped product from solidifying. Adanac often receive enquiries from users that have not considered this scenario and need to replace a seized un-heated valve with a jacketed version. Typical industries that use Jacketed Valves are Chocolate Production, Sulphur recovery, Pharmaceutical and Fertiliser Products.
Adanac manufacture both partially and fully jacketed valves. Fully jacketed valves can be Oversize Flanged, Wafer Pattern or Butt Weld type.
Adanac’s standard heating jacket is designed for a working pressure of 10barg at a temperature of 150°C however, Adanac's flexible approach to manufacturing allows for other operating conditions to be catered for.
Adanac Heating Jackets can be fully welded to the valve where the outer wall of the valve becomes the inner wall of the heating chamber. Alternatively, valves can be provided with clamp-on type jackets allowing for easy replacement of the valve without the need to replace the heating jacket.
Adanac Heating Jackets are suitable for a variety of heating media including Hot Water, Steam and Hot Oil. Although the standard jacket connection is threaded, alternative connections are available to suit the user’s particular application including, Socket Weld, Butt Weld or Flanged.
Valve materials include Carbon (ASTM A105, A216 WCB), Low Temperature Carbon Steel (ASTM A350 LF2, A352 LCB/LCC) and Austenitic Stainless Steel (ASTM A182 F316-L, A351 CF8M). Heating Jacket materials include Carbon Steels (BS EN 10025 S275JR) and Austenitic Stainless Steel (ASTM A240 316-L)
