WARNING: Installation, usage and maintenance of this product<br />
must be in compliance with all Engineered Controls International,<br />
Inc. instructions as well as requirements and provisions of NFPA<br />
#54, NFPA #58, DOT, ANSI, all applicable federal, state, provincial<br />
and local standards, codes, regulations and laws.<br />
The pneumatic actuator should be installed after valve is mounted<br />
in vessel, but prior to attaching pump or piping, with the valve in the<br />
closed position.<br />
Inspection and maintenance on a periodic basis is essential.<br />
Installation and maintenance should be performed only by qualified<br />
personnel.<br />
Be sure all instructions are read and understood before installation,<br />
operation and maintenance. These instructions must be<br />
passed along to the end user of the product.<br />
CAUTION: Contact or inhalation of liquid propane, ammonia and<br />
their vapors can cause serious injury or death! NH3 and LP-Gas<br />
must be released outdoors in air currents that will insure dispersion<br />
to prevent exposure to people and livestock. LP-Gas must be kept<br />
far enough from any open flame or other source of ignition to<br />
prevent fire or explosion! LP-Gas is heavier than air and will not<br />
disperse or evaporate rapidly if released in still air!<br />
Foreword<br />
The A3217FPA Pneumatic Actuator is designed for use with the<br />
A3217F Series 3" Flanged Internal Valves.<br />
The A3217FPA provides a convenient means of opening and closing the<br />
internal valve from a remote location on DOT MC331 transport and<br />
delivery trucks as well as stationary storage tanks.<br />
How the Pneumatic Actuator Works<br />
The pneumatic actuator can be pressurized with either air or nitrogen.<br />
The actuator’s diaphragm rod moves the valve’s operating lever to the<br />
open position when pressure is applied. Upon loss of pressure, the<br />
valve’s operating lever returns to the closed position.<br />
The A3217FPA operates with a minimum pressure of 50 PSIG and a<br />
maximum operating pressure of 150 psig.<br />
The pneumatic actuator is compatible with existing air interlock systems.<br />
It also provides a convenient means of operating a number of<br />
internal valves on stationary tanks at bulk plants from remote locations.<br />

Actuator for 3" Internal Valve<br />
Installation and Operation<br />
Manual Actuator Removal<br />
NOTE: If the manual actuator is present, it must first be removed<br />
before installation of the pneumatic actuator. Refer to Diagram 1<br />
during removal of the manual actuator.<br />
1. Remove cotter pin from lever and remove lever from valve stem.<br />
Leave the nylon washer in place.<br />
2. Remove both lever stop pins from valve face.<br />
Pneumatic Actuator Installation<br />
NOTE: Lubricant compound #11550-215, or the equivalent, should be<br />
applied in a light coating when specified. Torque tolerance is ±10 in/lbs.<br />
Refer to Diagram 2 during assembly of the pneumatic actuator.<br />
1. Remove the clevis and clevis locknut from the air chamber shaft.<br />
Remove the cotter pin and pivot pin from the clevis.<br />
2. Assemble the air chamber to the bracket using the air chamber nuts<br />
and lock washers. Center the air chamber shaft in the clearance hole<br />
of the bracket. Tighten air chamber nuts to 375 in/lbs.<br />
3. Reassemble the clevis locknut and clevis to the air chamber shaft.<br />
Adjust the clevis so that the center of the pivot pin hole is 2 3 /4" from<br />
the bracket with the pivot pin holes in the horizontal plane. Lock the<br />
clevis in place with the clevis locknut using 200 in/lbs torque.<br />
