All piston
actuators are quipped with
a gas over oil tank to assure
smooth operation and
prevent valve damage.
Proper fluid level is
important.
ORBIT
21
To check the fluid
level, read the nameplate to
determine if the actuator is
the LG type or the LS type.
If the nameplate is illegible
or missing DO NOT attempt
to check the fluid level
without consulting ORBIT
Representative.
15
ORBIT diaphragm
actuators equipped with a
manual close mechanism
have an additional upper
lube point located on the
manual closer stem. Spring
close diaphragm actuators
have no upper lube point.
16
Diaphragm actuators
equipped with a two way
manual mechanism have an
upper lube point that is
only accessible when the
manual mechanism is in the
open position.
17
All piston
actuators have a lower lube
point above pressure line
pressure.
ORBIT
18
ORBIT piston actuators
equipped with a manual
close mechanism have an
additional upper lube point,
which lubricates the manual
mechanism stem.
Piston actuators with a two
way manual mechanism
have no upper lube point.
19
Piston actuators
equipped with two way
gear mechanism have a
lube point on the gear box
as shown.
22
To check fluid level for
the LG type, CLOSE the valve.
This forces the hydraulic
fluid from the actuator into
the gas over oil tank.
In the closed position the
fluid should reach the level
indicated in the chart below.
If the fill plug is
removed in the OPEN position,
actuator pneumatic pressure will be
encountered if the system is under
pressure. Personal injury and/or
damage to property may result.
WARNING!
CORRECT FLUID LEVEL FOR LG TYPE PISTON
Actuator Tank Size Fluid Level Capacity
in. mm Hole gallon litre
LG-124 12 x 19 305 x 483 one only 5 19
LG-185 14 x 27 356 x 686 bottom 12 45
LG-205, 206 14 x 27 356 x 686 top 15 57
LG-206 14 x 33 356 x 838 top 18 68
LG-266 16 x 38 406 x 965 top 28 106
23
To check the fluid level
for the LS type piston
actuator, OPEN the valve.
This forces the oil from
above the lower piston into
the gas over oil tank. The
fluid should reach the fill
plug level indicated in the
cart below.
If the
fill plug is removed in the CLOSED
position, actuator pneumatic
pressure will be encountered if the
system is under pressure. Personal
injury and/or damage to property
may result.
WARNING!
