Noshok® 3070-MFC is a 3 valve, hard seat, double block & bleed needle valve part of the 3070 series. It combines isolating and venting in a single valve, eliminating the need for tubing and fittings. The block valve isolates the downstream process fluids, and the bleed valve exhausts upstream fluids, enabling instruments to be removed without disturbing the permanent piping installation on the bottom. The ¼” NPT vent plug is located 90° to the left and may be removed and replaced with exhaust piping to direct the fluids to a safe location.
