Description
K-7 Series Unloader
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 for 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 adjustments. Minimum 5% bypass is required for proper
operations. Unique balance principle: eliminates high pressure
in all lines while unit is in bypass mode.
