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.
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.
Eliminates 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.
