For many years industrial valve manufacturers have addressed instrument isolation with many variations of knife-gate, ball and wedge-gate valves with marginal success. The challenge has been to provide instrument isolation in order to periodically calibrate the level transmitter while creating a bubble tight seal. Often the valves did not provide Bubble tight sealing and thus the transmitter could not be removed due to safety issues. This meant that the tank would have to be drained in order to remove the transmitter. What to do with all that product? Our primary objective was to design a true “Isolation Valve” that encompassed the solutions to all the problems associated with the level transmitter isolation. We did just that.
