The HM73 is a versatile and economical angle pattern shutoff valve. It is the easiest way to change direction from horizontal to vertical mounting of a transmitter or flow computer on an orifice fitting or orifice flange union. To change direction, just add this between your direct mount system and the HM37 five valve gas pattern manifold. In addition to two additional block valves, it has two drain ports and two more ports for adding an additional measurement device. As is the case for the HM37, the HM73 is a large bore and has a soft seat for tight shutoff.
