The D-060-C HF, D-062 HF series Combination Air Valve has the features of both an air release valve and an air & vacuum valve. The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.

Product Features

  • Combines the features of both an air & vacuum valve and an air release valve.
  • Triple function:
    • Air & vacuum component discharges large volumes of air during filling of the system.
    • Air & vacuum component admits large volumes of air during drainage and at water column separation.
    • The air release component releases entrapped air in pressurized systems.
  • All main flow cross-sections are equal or greater than the nominal port area.
  • Aerodynamic design enables high flow rates of air both at intake and at discharge.
  • Special orifice seat design: combination of Stainless Steel and E.P.D.M. rubber assures long-term maintenance-free operation.
  • Available in flange sizes: 1" - 10" .
