MODELS C27 - C53
SPRING/DIAPHRAGM LINEAR PNEUMATIC ACTUATORS
SECTION I
I. DESCRIPTION AND SCOPE
Actuator models C27 and C53 are multi-spring, single acting, spring opposed, linear actuators used with Cashco sliding stem (linear), globe-style control valves. The “R” denotes“ reverse”acting arrangement; the “D” denotes “direct” acting arrangement and are reversible in the fi eld.
“D” = Direct action; on increasing air loading pressure,the actuator stem extends. Fail-safe position is with the stem retracted.
IOM-C27-C53
12-13
“R” = Reverse action; on increasing air loading pres­sure, the actuator stem retracts. Fail-safe position is with the stem extended.
When coupled with a globe-style control valve with pushdown to close action, a “D”- direct acting actua­tor will provide valve “fail open” action;“D” = ATC-FO. When coupled with an “R” - reverse acting actuator, will provide valve “fail closed” action; “R” = ATO-FC.

III. INSTALLATION
A. Orientation:
SECTION III
B. Air Supply:
1. Recommended actuator major axis orientation with any model of Cashco control valve body, is upwards in a horizontal pipe.
2. Actuator axis may be horizontal when valve is in a vertical pipe.
3. Outdoors, all installations must be oriented any angle from horizontal-to-vertical.
4. Models C27 and C53 actuators are not recom­mended for installation oriented downwards in either “D” or “R” action.
5. In no case is additional weight to be applied to the actuator when installed in an orientation other than vertical; i.e. the valve is unsafe as a “step” to support personnel.
IV. MAINTENANCE
A. General:
1. Hereafter, all maintenance, disassembly,
etc., is assumed to be done in an indoor shop.
2. An actuator assembly (AA) is unitized with a body assembly (BA). Reference should be made to the body IOM for instructions about the specifi ed body assembly (BA) utilized with the actuator.
3. Where the body is not being removed from the actuator, special care MUST be exhib­ited to prevent valve stem rotation during any disassembly or reassemble for all valve models. Following this procedure will ensure not damaging seating surfaces.
4. Remove instrument tubing, airset, positioner, and any other accessory that maybe mount­ed on the control valve unit (AA, BA).
5. All indicated Item Numbers that are with re­spect to body (BA) IOM will be in parenthesis and underscored; i.e. (20); the same is true for positioner parts. All Item Numbers that are with respect to this manual are not un­derscored; i.e. (19).
1. Recommendation is that a desiccant dried, instrument quality air supply be used. Such a supply is recommended for out­doors installations, and is required in ar­eas of freezing weather conditions.
2. If air supply contains moisture and/or lu­bricating oil, the air should be fi ltered with a coalescing type of fi lter prior to use in stroking the actuator.
3. Failure to remove moisture will cause cor­rosion to internals of casings (1,2).
4. Connections for the air supply are 1/4” fe­male NPT. A suitable pipe thread sealant is recommended to be used when install­ing the pipe or tube fi tting. Exhibit care to prevent the sealant from getting inside the tube/pipe.
SECTION IV
B. Diaphragm Removal/Replacement:
NOTE: Actuator (AA) must be separated from
the body (BA) in order to replace O-rings (15, 16 &17) and diaphragm (7). Refer to specifi ed body (BA) IOM for instructions to remove actuator (AA).
NOTE: If actuator (AA) has Handwheel refer to
Step E and remove.
1. Secure the yoke (3) in a vise. Orient with the (AA) upwards.
2. All air pressure must be released from the actuator casings (1,2).
3. Take note of alignment of supply ports on top and bottom cases (1,2); used to assist with ori en ta tion when actuator is re- as sem­ bled.
WARNING
SPRINGS UNDER COMPRESSION! To relax spring com-
pression remove case bolting equally in an alternating pattern. Ensure that all "short" bolting is removed rst.
