SEALS
Through the use of a wide range
of seals, the ASC actuator can
be employed at high or low
temperatures.
DUAL SHAFT
Can facilitate easy change from open to fail
close operation and vice-versa. Also serves
as connection for standard limit switches in
accordance with Namur.
SCOTCH YOKE SYSTEM
The scotch yoke system is designed
especially for quarter turn valves, permitting
a torque amplification at beginning and end
of stroke.
PROTECTION
The ASC actuator is designed with a
coated cylinder. This fluoropolymer
coating guarantees resistance to
corrosion and limits friction thereby
improving output. Its long term
resistance ensures great reliability and
low maintenance.
TRAVEL STOPS
Travel stops adjustable in
both directions adjustable
+/-5°. All quarter turn
valves can thus be
operated under the best
safety conditions.
CONSTRUCTION
The SARASIN ASC actuator has an integral cast housing for
improved mechanical resistance and is completely impervious to
corrosion even in the most aggressive environments.
