Feed Rate Control Valves, Manual Operation

FEED RATE CONTROL VALVES

Turn valve (24) marked “R”on top of housing, approximately 1-1/2 turns counterclockwise (open).

Turn the other valve (24) marked “F"on top of housing, clock- wise until closed (do not tighten too snugly).

Start the unit and slowly turn valve (24) marked “F",counter- clockwise (open) until the desired forward rate of feed is reached.

A final adjustment of the rate of return (retract) can be made with the valve (24) marked “R”on housing.

MANUAL OPERATION

Install button bleed valve (27) in either the “F"port located at top of valve housing or the “F"port located at the rear of valve housing. NOTE: Unused port must be plugged with pipe plug

(22).

Depress button bleed valve (27) marked “F"on valve housing. The unit will start in the forward (advancing) mode and contin- ue to feed forward until the adjusting screw “B”has depressed bleed valve (27) marked “R”to retract the unit. See set-up procedure.

A manual emergency retract button bleed valve (27) can be installed in “R”port at top of valve housing if desired. This valve can be used to immediately retract the unit in case of misaligned part or other emergency. Valve not furnished.

REMOTE OPERATION

Install a pressure bleed valve - ARO part number 9600 -in valve port marked “F"at either the top or rear of valve housing Connect pressure bleed valve - using 1/8” i.d. tubing - to a re- mote operated valve which, when actuated, feeds air pres- sure to the pressure bleed valve. Pressure bleed valve will bleed the air from "F" port of valve housing causing spool valve in housing to shift to the forward feed position, thus start- ing the forward stroke of the unit.

Install a pressure bleed valve - ARO part number 9600 - in valve port marked “R”at the top of the valve housing and con- nect - using 1/8” i.d. tubing -to a remote MANUALLY oper- ated valve. This valve is used as an emergency retract in case of a part misalignment or such only as the unit, when properly set-up and applied, will automatically retract and return to the start position. See set-up procedure.

Refer to page 10 for plumbing and schematic diagrams.

SPECIAL NOTE: The air inlet and remote ports of valve housing have tapered pipe threads and should not require the use of thread sealants, such as sealant tape or pipe joint compounds. Thread sealants, when used improperly, can contaminate air pas- sages and cause valve or unit to malfunction.

RECOMMENDED POWER AIR INLET SYSTEM

Your ARO self-feed tool is designed to deliver specific horsepower and thrust to achieve high rates of work. To assure the unit will develop this power, care must be taken that the power air inlet system is correctly sized to permit the proper rate of air flow. Shown is asystem for a single tool that will supply correct delivery. IMPORTANT‘-thetool is power rated when 90 p.s.i. is present at the tool during operation.

Shown below is the same system in schematic form.
