Chemoil Advance Technology supplies Jacketed Swing Check Valves from recognized manufacturers for process applications requiring automatic reverse-flow protection while helping maintain the temperature of temperature-sensitive process media. The valve combines a swing check mechanism with an external heating or cooling jacket around the valve body.

The swing check mechanism allows process flow in the intended direction and automatically closes when reverse-flow conditions occur. The external jacket provides a passage for a suitable heating or cooling medium to help maintain the temperature of the process fluid around the valve body.
