Maintenance
These actuators are noise-free and maintenance-free.
Careful installation will help ensure long-term reli-
ability and performance.
Operation
After the mechanical and electrical installations have
been completed, cycle the actuator to verify opera
-
tion. (See Illustrations 4 and 5.)
When power is applied to the actuator, the tem
-
perature of the heating element rises, causing the
solid expansion medium to expand and stroke the
attached valve body. The valve starts to open after
preheating for approximately 1 minute if the heating
element is switched on in a cold (room temperature)
state, and achieves the maximum stroke after (ap
-
proximately) another 3-1/2 minutes. At power-off,
the expansion element cools down, and the spring
closes the valve.
De-energized position (gap closed):
•
For MEP-3001s, the actuator shaft
is extended and the valve is closed.
•
For MEP-3006s, the actuator shaft
is retracted and the valve is open.
(Fully) energized position (gap open):
•
The MEP-3001 has been connected
to the power supply for at least
4-1/2 minutes. The actuator shaft is
retracted and the valve is open.
•
The MEP-3006 has been connected
to the power supply for at least
4-1/2 minutes. The actuator shaft is
extended and the valve is closed.
