Double Block and Bleed Plug Valves ( DBB ), are designed to provide high integrity, positive shut-off with the double block and bleed verification design. DBB Plug valves are used in critical applications where product contamination risks are high. These valves are found in Pumping Stations, Liquids Terminals, Aviation Terminals, Crude Oil and Refined products Metering and Measurement Equipment.


general twin seal & gENERAL tRU sEAL

Rapid seal abrasion is inherent in the designs of most ball and gate valves. The Cameron GENERAL Twin Seal & Tru Seal double-block-and-bleed plug valves reduce this constant wear by using two seating slips independently mounted on a tapered plug by dovetails, which mechanically retract from the seating surface prior to rotating. This provides a bubble-tight, verifiable dual seal without seal abrasion.


General 4-way diverter valve

The Cameron portfolio of GENERAL valves includes a four-way diverter design that features no-leak stream separation and a longer seal life. This valve does not rely on line pressure or hydraulic pressure for positive sealing.
