Three connection types.
PANAM® Double Block & Bleed valves cover the full instrument isolation spectrum — Flange-to-Pipe, Flange-to-Flange, and Pipe-to-Pipe configurations engineered for primary isolation, pressure transmitter mounting, and process bleed applications. All three families share the same SS316 construction with ball, needle, and combination internal configurations.
DBB options include NACE MR-0175, Fire Safe, lock handle, anti-static, gear-operated, and OS&Y bonnet options. Seat and seal materials cover Carbon Filled PTFE, PCTFE, Delrin, PEEK, PTFE, Grafoil, and FKM.
