SAFETY FIRST
2.0 SAFETY ISSUES
Read all instructions, warnings and cautions
carefully. Follow all safety precautions to
avoid personal injury or property damage
during system operation. Enerpac cannot be responsible for
damage or injury resulting from unsafe product use, lack of
maintenance or incorrect product and/or system operation.
Contact Enerpac when in doubt as to the safety precautions and
operations. If you have never been trained on high-pressure
hydraulic safety, consult your distribution or service center for a
free Enerpac Hydraulic safety course.
Failure to comply with the following cautions and warnings could
cause equipment damage and personal injury.
A CAUTION is used to indicate correct operating or maintenance
procedures and practices to prevent damage to, or destruction of
equipment or other property.
A WARNING indicates a potential danger that requires correct
procedures or practices to avoid personal injury.
A DANGER is only used when your action or lack of action may
cause serious injury or even death.
sgls.eps
WARNING: Wear proper personal protective gear when
operating hydraulic equipment.
undr.eps
WARNING: Stay clear of loads supported by hydraulics.
A cylinder, when used as a load lifting device, should
never be used as a load holding device. After the load has
been raised or lowered, it must always be blocked mechanically.
DANGER: To avoid personal injury keep hands and
feet away from cylinder and workpiece during
operation.
Dexceed.eps
WARNING: Do not exceed equipment ratings. Never
attempt to lift a load weighing more than the capacity of
the cylinder. Overloading causes equipment failure and
possible personal injury. The cylinders are designed for a max.
pressure of 350 bar [5,000 psi]. Do not connect a jack or cylinder
to a pump with a higher pressure rating.
danger.eps
Never set the relief valve to a higher pressure than the
maximum rated pressure of the pump. Higher settings
may result in equipment damage and/or personal injury.

The modular Holding Valve allows separate operation
of clamping fixtures with a single pressure source. This
valve is ideal for applications when fluid feed lines are
impractical. If system pressure is interrupted, the valve
will hold the pressure beyond the valve. To release system
pressure, rotate the valve handle in either direction 90° to
release and retract system pressure.
gge.eps
WARNING: The system operating pressure must not
exceed the pressure rating of the lowest rated component
in the system. Install pressure gauges in the system to
monitor operating pressure. It is your window to what is happening
in the system.
hosbnd.eps
CAUTION: Avoid damaging hydraulic hose. Avoid sharp
bends and kinks when routing hydraulic hoses. Using a
bent or kinked hose will cause severe back-pressure.
Sharp bends and kinks will internally damage the hose leading to
premature hose failure.
®
drag.eps
Do not drop heavy objects on hose. A sharp impact may
cause internal damage to hose wire strands. Applying
pressure to a damaged hose may cause it to rupture.
IMPORTANT: Do not lift hydraulic equipment by the
hoses or swivel couplers. Use the carrying handle or other
means of safe transport.
CAUTION: Keep hydraulic equipment away from
flames and heat. Excessive heat will soften packings and
seals, resulting in fluid leaks. Heat also weakens hose
materials and packings. For optimum performance do not expose
equipment to temperatures of 65 °C [150 °F] or higher. Protect
hoses and cylinders from weld spatter.

inject.eps
DANGER: Do not handle pressurized hoses. Escaping
oil under pressure can penetrate the skin, causing serious
injury. If oil is injected under the skin, see a doctor
immediately.
bdyhit.eps
WARNING: Only use hydraulic cylinders in a coupled
system. Never use a cylinder with unconnected couplers.
If the cylinder becomes extremely overloaded, components
can fail catastrophically causing severe personal injury.
IMPORTANT: Hydraulic equipment must only be serviced
by a qualified hydraulic technician. For repair service,
contact the Authorized ENERPAC Service Center in your
area. To protect your warranty, use only ENERPAC oil.
sman.eps
WARNING: Immediately replace worn or damaged parts
by genuine ENERPAC parts. Standard grade parts will
break causing personal injury and property damage.
ENERPAC parts are designed to fit properly and withstand high
loads.
3.0 INSTALLATION
1. The unit can be mounted in any direction. Secure the valve to
any flat surface with two 1/4˝ mounting bolts.
2. Connect the pressure line from your pressure source to the
hydraulic inlet port on the side of the valve.
3. Connect another line from the hydraulic outlet port at the end
of the valve to your cylinder or tool.
4.0 OPERATION
The valve will hold pressure when the lever arm is pointing to
the “CLOSED” position. It will release pressure when the arm is
turned 90° in either direction to “OPEN”. The lever arm will lock in
the “OPEN” position when it is turned past 90°.
