With one double-seated bubble-tight valve, the twin seal plug valve serves as an alternative to a traditional two-valve system. The upstream and downstream seals provide the same function as two block valves. The body serves as a spool piece, and the body bleed verifies seal integrity.
Twin seal plug valves avoid abrasion 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.
Twin seal plug valves are frequently used in a variety of industries, including oil and gas. Relevant applications include pipeline pumping stations and terminals, refinery bulk loading terminals, aviation fueling systems, and crude oil and refined products metering and measurement systems.
Bayport Technical's Twin Seal Plug Valve Cutaway (108-TSPV) allows individuals to see and identify the internal components of the valve. The valve can be taken apart and reassembled for training purposes.
