The junction is based on the proven principle of the I.S.T. T-ring valve. By interconnecting, two pig lines can be opened to each other, thus connecting different plant areas. Both pig lines can be completely pigged through this valve. Due to this possibility of connecting the connected pig lines, the T56 valve allows a very high flexibility in the daily application.
