Specifications
Description
Combination full port shut-off valve and drain valve used
to connect an expansion tank to the system. It is important
that the pre-charge in an expansion tank be maintained at
the proper pressure at all times. This pressure is the lowest
system operating pressure. When the tank’s pressure is
adjusted, there should be no system liquid in it. This
pre-charge should be checked and adjusted when:
• Tank is first installed
• If system is started or operating with the incorrect
tank pre-charge
• Annually to assure proper pre-charge pressure at all times
The TPV (Tank Purge Valve) is ideal for this as the tank can
be isolated from the system, drained and the pre-charge
checked and adjusted without draining or shutting down
the system.
The TPV also serves as a service valve should the tank need to
be removed or have the bladder changed. These valves are
furnished standard with a drain valve with a standard 5/8”
hose connection.
These valves are not recommended to be used on
potable water tanks.
