Service Manifold Model 293-12B Owner's manual

DescriptionNameItem
an actuator and servovalve. The control manifold also contains
a low pressure solenoid valve, a high-pressure solenoid valve,
a main valve, a slow turn-on accumulator, and a pressure gage
to control a single hydraulic channel.
Indicates system hydraulic pressure.Pressure Gage2
Fills to extend the pressure rise time and slowing the rate at
which the main control valve operates.
Slow Turn-On Accumulator3
Allows low-pressure hydraulic fluid to be output to the hydraulic
channel.
Low-Pressure Solenoid Valve4
Allows high-pressure hydraulic fluid to be output to the hydraulic
channel.
High-Pressure Solenoid Valve5
Sets the low-pressure output of the hydraulic channel.Low-Pressure Adjustment6
Reduces pressure and flow fluctuations at the pilot pressure
port.
Pilot Pressure Accumulator
(optional)
7
Reduces pressure and flow fluctuations resulting from changing
system demands.
Pressure Accumulator8
Filters the hydraulic fluid as it is input to the pilot pressure
circuit. The filter has a visual indicator to signal when the
element requires replacement.
Pilot Pressure Filter (optional)9
Filters the hydraulic fluid as it is input to the main manifold. The
filter has a visual indicator to signal when the element is
requires replacement.
Main Filter10
Reduces pressure and flow fluctuations resulting from changing
system demands.
Return Accumulator11
Distributes hydraulic fluid from the main manifold to up to four
control manifolds.
Distribution Manifold12
Distributes hydraulic fluid between the HPU and up to two
control manifolds or a distribution manifold.
