Double Block And Bleed And Sampling Valves

Because of the double port seals in both directions and the sealed isolation of the chamber below the plug and the areas around the plug, 900 to the port openings, a drainage connection into the plug cavity may be drilled and tapped through the body from either side or the bottom.

A 1/4" drain connection is standard, but other sizes can also be provided. Specify connection size; length as indicated on the drawing and whether the bleed valve is required. A FluoroSeal Fig. 152/302SE is ideally suited as the bleed valve.
