Description
The D-060-C HF Combination Air Valve has the features of both an Air-release valve and an Air/vacuum valve. The Air-release component of the D-060-C HF was designed to automatically release to the atmosphere small pockets of air as they accumulate at local high points along a pipeline when the pipeline or piping system is full and operating under pressure. The Air/vacuum component was 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.

Main Features
• Aerodynamic design enables high flow rates of air (Inflow and outflow).
• All flow cross-sections are equal or greater than the nominal port area.
• Reliable operation reduces water hammer incidents.
• Dynamic design allows high velocity air discharge; Preventing premature closing.
• Lightweight, small dimensions, simple and reliable structure.
• Special orifice seat design: Stainless steel SAE 316 and E.P.D.M rubber, assures long-term maintenance free operation.
• Screen protected outlet.
• The upper screen is protected with protective "umbrella".
• Working pressure range:
- D-060-C HF: 3 -285 psi.
- D-062 HF: 3 -360 psi.

Valve Selection
• D-060-C Vandalism protect by metal casting body.
• D-062 Vandalism protect by metal casting body for 360 psi.
