Steam ­jackets for valve bodies

February 2015 Valves, Actuators & Pump Control

Mitech designs, fabricates and tests its steam jackets to ANSI B16.34 – 1998. The steam jackets are designed to keep the valve body at a set temperature by hot substance such as steam which is circulated around the valve body to keep the fluid inside both warm and in a liquid state. The steam circulates in the annular space between the jacket and the vessel walls and allows heat to be transferred through the wall of the vessel.

Mitech’s hub end Inline Globe Control valve body is used as a base and is modified to incorporate the steam jacket. Flange ends become integral, while the flange drilling incorporates blind tapped holes.

All valves are pressure and leak tested before and after jacketing. There are numerous jacketing considerations, including flange size, full or partial coverage, types and locations of heated medium connections, materials, bonnet jackets or additional heat coverage for specific areas.
