This unloading valve is a flow-through design
and should be mounted on the discharge line of
the pump in any position (vertical or horizontal)
which allows easy access to the adjusting bolt.
A pressure gauge should be installed on either
side of the port of the unloader to accurately
read pressure during adjustment.
Minimum 5% bypass is required for proper operation.
Features all stainless and brass internal parts.
No external moving parts or springs.
Unique balance principle: eliminates high
pressure in all lines while unit is in bypass mode.
Elimiates pressure peaks normally generated
by conventionally designed unloaders.
Dual gauge ports. Maximum Temperature: 165 F.
Inlet Port: 3/8" FPT.
Outlet Port: 3/8" MPT.
Bypass Port: 3/4" MPT.
