FluoroSeal® Plug Valves offer double port seals in both directions as well as a sealed isolation of the chamber below the plug and the areas around the plug at 90° to the port openings. A single valve can isolate either upstream or downstream, thus eliminating the need for the traditional two double block valves — a definite reduction in cost and maintenance, especially in processes involving large diameter lines.
To achieve the Double Block and Bleed combination, a drainage connection into the plug cavity is added by drilling and tapping through the bottom of the valve body.
FluoroSeal® Double Block and Bleed valves offer a 1/2” (12.7 mm) drain connection as standard, but other sizes can also be provided. Flexibility in connection size, length, and variety in availability, means that no matter what your space or process, a FluoroSeal® Double Block and Bleed valve will successfully fulfill your isolation needs.
A FluoroSeal® Fig. R152/302SE is ideally suited as the bleed valve.
FluoroSeal® Double Block and Bleed Valves have an outstanding performance record in many industries including:
