Figure 16: Installation of Air Release Valve
Always install the valve inlet line between the pump discharge port and the
discharge check valve on the non-pressurized side. The valve inlet opening
has 1-inch standard NPT pipe threads. It is located at the large end of the
valve body.
The valve outlet opening is at the opposite (small) end of the valve body. It
also has 1-inch standard NPT pipe threads. A bleed line that drops back to
the wet-well or sump must be connected to the valve outlet. It is imperative
that the bleed line is the same size or larger than the inlet piping. When
possible, do not use elbows in a bleed line made of piping.
NOTE:
Every WSP™ ARV should be modified to accommodate an independent
bleeder line that can slope backward toward a sump or the wet-well (Figure
17). When more than one WSP™ ARV is installed in a system, each valve
must be fitted with an independent bleeder line. Never use a common
manifold pipe. Contact your local WSP™ distributor or the factory for
information about WSP™ ARV installation for individual applications.
