nnnnPower Unit
nnnnI Actuator power source for
nnnnnatural gas pipeline applications.
nnnnI This closed system will not
nnnnexhaust any gas to the atmosphere.
nnnnDesign Philosophy
nnnnShafer has developed the Electro • Hydraulic Power
nnnnUnit as an alternative to gas/hydraulic powered ac-
nnnntuators for environmentally sensitive applications.
nnnnThe Electro • Hydraulic Power Units are designed to
nnnntake advantage of the available gas pressure in the
nnnnpipeline. However, unlike the conventional gas/hy-
nnnndraulic systems, the Electro • Hydraulic Power Units
nnnnare totally closed systems and do not exhaust natural
nnnngas into the atmosphere.
nnnnExisting actuators with gas over oil type power
nnnnsupply may be converted, in the field, with an
nnnnElectro • Hydraulic Power Unit, corrosive or detri-
nnnnmental atmospheric conditions.
nnnnApplications
nnnn• Actuator power source on natural gas pipeline
nnnnapplications.
nnnn• Alternate actuator power source to gas over oil
nnnnapplications where 120 VAC, single phase electri-
nnnncal power is available.
nnnn• For new or existing equipment.
