The D-060 SB is a complete product package that combines the reliable and efficient properties of the A.R.I. D-060 combination air valve with the added feature of a sub-surface valve. The valve is buried and operates below ground, whilst service and maintenance operations of the unit are performed entirely from the surface.
The D-060 Combination Air Valve has the features of both an air release valve and an air & vacuum valve. The valve is designed to automatically release small pockets of built up air to the atmosphere during operation, and also automatically discharges or admits large volumes of air during the filling or draining of a pipeline.

Product Benefits
Gear Box Operated Shut-off Valve
Enables the disconnection and removal of the D-060 air valve from its subsurface housing, even when the system is under pressure.
Surface operation
All Maintenance is conducted above surface, removing safety considerations for confined spaces.
Safety Mechanism
Unless the shut-off valve is in the “closed” position and the internal pressure is released, a safety mechanism stops the accidental extraction of the air valve.
