SD-10 | Underground Air Valve
Description
A.R.I. model SD-010GB is a 3" inlet, gear box driven horizontal sliding disc valve designed for underground and confined space installations. The gear box is activated by a vertical operating rod (enables above ground operation of underground installations). The valve provides fluid-tight sealing up to 25 bar (365 psi) working pressure and is installed horizontally between the pipeline and the user's device.
Integral to the valve is either a 2" or 3" threaded or quick connection adaptor outlet. The 3" adaptor has an additional 1 ½" NPT female threaded orifice perpendicular to its vertical access, which can be used as a flushing outlet.
The quick connection adaptor has a built in safety mechanism to prevent the accidental removal of the user's device while there is open flow through the valve. The disc valve must be in the closed position before the user's device can be disconnected from the quick connection adaptor.
