VPV Controls
Single Stage Compensator
The single stage control for normal pressure compensation
is a good choice where speed is important and remote
capability is not required. This control available on VPV 16,

Two Stage Compensator
The two stage pressure compensators are the platform
for most VPV controls. A remote port is standard and
may, or may not be enabled according to the circuit
design. This is the smoothest of the standard pressure
controls, and is the standard pressure compensator for
VPV 45–164.

Load Sense Compensator
Load sense allows the user to maintain constant flow
regardless of changes in load or in pump shaft rotational
speed. The Whisper™ Pump load sense accomplishes
this by using an external orifice and continually senses a
pressure drop of 100 PSI across this orifice. The mini-
mum ∆P is 200 PSI, however the pressure drop can be
adjusted to meet circuit requirements. Consult factory.
