EL-O-Matic F-Series Actuators
!
WARNING
Stay away from moving parts to prevent serious injury. When test cycling
the actuator and valve assembly by applying pressure to the A or B port, be
aware that there are moving parts like pinion top, actuator to valve coupling
and the valve blade, ball, plug, etc.Isolate the piping system on which an
actuator-valve assembly is installed, when removing this assembly, and relieve
any media pressure that may be trapped in the valve cavities before removing
the actuator for maintenance.

Operation

!
WARNING
When rotating the actuator stem or shaft with loading pressure applied, use
caution to keep hands and tools out of the actuator travel path. Personal injury
and property damage is possible if something is caught between the actuator
stem and other control valve assembly parts.

Operating media

1. Use clean, dry or lubricated air or inert gas.
2. Maximum Operating Pressure (MOP) = 8.3 barg/120 psig
MOP is the pressure required to produce the maximum
rated torque at the break position for all actuators.
Pressure should not exceed MOP during valve rotation.
MOP should be the maximum pressure regulator setting.
!
WARNING
It can be assured that the housing will not rupture or burst when applying
10 bar of pressure but the cycle function cannot be guaranteed as it totally
depends on the time span to which actuator is subjected at 10 bar and the
frequency at which these pressure peaks occurs. Every time this peak occurs
will, for sure, have a significantly negative effect on the life expectancy of
the actuator.
