soon as the system pressure equals the set
• Great new design that can be used on pressure. As long as the system is connected
pallet fixtures disconnected from a to the power source, the valve will open again,
power source, since no return line is if additional fluid is required to maintain the
needed downstream pressure. Valve is also ideal for
use on palletized (uncoupled) systems.
• Allows fine tuning of the clamping force
for selected components while keeping UNIQUE FEATURES: In normal systems
others at full pressure (connected to power source) valve performs
as a true pressure reducing valve, and in
• Holds reduced pressure to exact Palletized (uncoupled) systems as a pressure
setting, regardless of input pressure closing valve.
• Zero leakage poppet design DESIGN CONSIDERATIONS: When using
this valve in series with other valves (clamp/
unclamp valves, sequence valves, etc.,) the
pressure reducing valve must be the one
closet to the clamp(s) that it is protecting.

recommended that a pressure relief valve be
included to prevent pressure in creases in the
downstream (low pressure) side of the system.
