PRESSURE POWER SOURCES.

10,000 psi

• May be used to operate two separate, single-acting tools (with integral valves) independently, without
need for additional manifold.
• Control valve included. Other Power
Team valves available as an option
to suit your specific application, if
needed; consult factory.

• Applications include utilities,
railroads, construction, riggers
and others.

cylinders, jacks, and tools such
as crimpers, spreaders, cable
cutters, or tire tools. Version for
use with double-acting torque
wrenches available.

• Compact and rugged for use inside
a utility vehicle aerial bucket or
stowing in a vehicle.
• No reservoir level to maintain;
uses low pressure system as
oil supply.
• Has 3⁄8" NPTF ports; compatible
with standard fittings for low and
high pressure systems.

† For maximum efficiency, recommended input flow is 5 gpm at a maximum
pressure of 2,000 psi. Higher flows and/or pressures must be compensated for at the system pump (e.g., relief valve, variable flow devices, etc.).
