3070-MFC

3070-MFC is a 3070 series double block & bleed, hard seat, 3-valve needle valve. It combines isolating and venting in a single valve, eliminating the need for tubing and fittings. 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.
