Description

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 that can be buried below ground. A specially designed gear box operated horizontal sliding disc valve - situated at the base of the D-060 SB assembly - allows for the air valve disconnection and maintenance from ground level.

This gear box operated shut-off valve is equipped with a safety mechanism enabling disconnection and removal of the D-060 air valve from its sub-surface housing, even when the system is under pressure. Since service and maintenance operations of the unit are performed entirely from the surface, there is no need for safety considerations associated with confined space entry.

The D-060 Combination Air Valve has the features of both an air release valve and an air & vacuum valve.
