Rapid seal abrasion is inherent in the designs of most ball and gate valves. The double block-and-bleed (DBB) Cameron GENERAL VALVE Twin Seal plug valve reduces this constant wear by using two seating slips mounted independently 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.
