producer recommends to pipe the valve first and then mount the actuator on the valve body.
Application and miantenance
The valves RV 111 COMAR line are suitable for such application where medium is water or air. Further it is
suitable for cooling agents and other non-aggresive liquid and gas media in tempe2°C to +150°C.
Maximum operating temperature can be lower depending on used actuator. For actuator series ANT
t
max
=150°C, for actuators series SSC t
max
=110°C and for actuators series SQS t
max
=130°C. If equipped with
hand wheel, the valve can be used up to t = 130°C.
The valves are maintenance-free they do not require any preventive checking during operation and service.
Malfunction and its solving

-Malfunction detection
The following malfunction can be detected actuator malfunction / the valve malfunction. First dismount the
actuator of course with power supply cable being disconnected. Then check the valve function with the aid of
hand wheel which is part of the actuator. In case the stem with plug moves and stops against the seat without
any problems, the problem relates to the valve. If the plug does not reach the seat position, the problem relates
to the actuator.
-Actuator Malfunction
Send the dismounted actuator back to the producer who shall inspects the malfunction and replace it with the
new one or make a repair. In the time of actuator replacing, the valve can be actuated with its hand wheel not
with the hand wheel of the actuator.
-Valve Malfunction
Possible cause of malfunction getting of impurity into the valve. The valve should be removed from the pipeline
and its inner parts checked and impurities removed. The valve body itself cannot be dismounted. In case the
problem cannot be solved, take the steps according to points a), b) or c).
a)Send the valve to the address of LDM servis, spol. s r. o., where the valve will be inspected and changed or
