Changeover Valve
The entire valve body is covered with a jacket that allows the hot fluid to be introduced into the jacket to maintain the temperature of the fluid. Steam flushing can also be added. This design makes the series of safety valves suitable for easily solidified fluids. The jacketed valve will also have a bellows construction that minimize the effects of back pressure and prevents spring
corrosion.
