Abstract
A valve includes a body and a gate disposed in the body. The gate is configured for motion between a position to permit fluid flow through the body and a position to restrict fluid flow through the body. At least one seal is disposed in at least one channel on the gate, wherein the at least one channel is configured to: a) receive a fluid to urge the at least one seal outward from the channel; b) release the received fluid to permit the at least one seal to retract into the channel; and c) cycle between (a) and (b). A method of operating a valve.
