The Victaulic Series 779 Venturi-Check valves provide a versatility of service unlike flow measuring device. The
CAD-designed hydrodynamic inlet profile provides a natural venturi as part of the valve. The inlet is drilled,
tapped and plugged, ready to receive the flow kit (included).
The venturi-like taps provide much greater measurement accuracy than taps placed across the valve seat. Valve
turbulence and interference across the valve seat need not be a consideration. Twin taps on both sides of the
valve provide positioning of measurement outlets for convenient meter connection.
Every valve is factory tested and rated to 300 PSI (2065 kPa) working pressure. All sizes can be installed in
horizontal or vertical position and provide leak-free sealing under conditions as low as five feet (1.5 m) of head
pressure.
