* - # 4 SPRING SET IS STANDARD

BI-DIRECTIONAL TRAVEL STOP INSTRUCTION Bradford Actuators feature bi-directional pinion travel stops. Stops located on the side of the actuator allow a full ±5˚ of valve travel adjustment, giving a guaranteed range of adjustment between 80˚ and 100˚ of actuator travel. These travel stops are designed to absorb the maximum rated torque of the actuator and the maximum impact loading associated with recommended stroke speed. Operation Adjustment of the counterclockwise and clockwise rotation limits are accomplished by turning the respective left and right stop adjustment screws to increase or reduce the output rotation angle.

ACTUATOR OPERATION Double-Acting (Top View)

P2

P1

For a clockwise output, apply pressure to P2. This forces the pistons to move to the center resulting in the linear piston travel converted to clockwise rotation of the pinion. The air volume between the pistons is exhausted at P1.

P2

P1

For a counter-clockwise output, apply pressure to P1. This forces the pistons to move away from the center resulting in the linear piston travel converted to counter-clockwise rotation of the pinion. The air volume outside each piston is exhausted at P2.

Spring Return (Top View)

P2

P1

For a clockwise output, the spring energy forces the pistons to move to the center resulting in the linear piston travel converted to clockwise rotation of the pinion. The air volume between the pistons is exhausted at P1, while the volume outside the pistons is vented at P2.

P2

P1

For a counter-clockwise output, apply pressure to P1. This forces the pistons to move away from the center, compressing the spring sets, and resulting in the linear piston travel converted to counterclockwise rotation of the pinion. The air volume outside each piston is exhausted at P2.

NOTE: When Reverse Rotation is required, the pistons can be inverted in the housing. This will result in a clockwise rotation when pressure is applied to P1 and a counterclockwise rotation when P1 is vented.

MAINTENANCE & OPERATING INSTRUCTIONS BRADFORD ACTUATOR OPERATION NOTE: For optimal operation, BRADFORD actuators should be run with a supply of clean, lubricated air. SPRING RETURN ACTUATORS Air to PORT P1 (the right hand port) causes the actuator to turn CCW. Loss of air to PORT P2 causes air to exhaust and the actuator turns CW. This is the FAIL CLOSE operation. DOUBLE ACTING ACTUATORS Air to PORT P1 (the right hand port) causes the actuator to turn CCW. Air to PORT P2 (the left hand port) causes the actuator to turn CW. ADJUSTING OPEN AND CLOSED STOPS BRADFORD actuators allow for ± 10˚ adjustment in both the open and closed positions. The stop adjustment bolts are located above the air ports (22 & 23). The right hand bolt allows for adjustment in the closed position; the left hand bolt allows for adjustment in the open position. A clockwise turn of the left bolt results in clockwise movement of the pinion; a counterclockwise turn of the bolt results in counterclockwise movement of the pinion. Loosen nut #23 and adjust screw #22. Re-tighten nut after adjustment to secure position.

DISASSEMBLING STANDARD ACTUATORS IMPORTANT: Before beginning disassembly, ensure that the air supply to the actuator has been disconnected, all accessories have been removed and that the actuator has been dismounted from the valve. 1. Loosen the end cap fasteners (8) with a wrench (size varies depending on actuator model). On the spring return actuator, alternate 3 to 5 turns on each fastener until the springs are completely decompressed. Use caution in removing the cap since the springs are under load until the fasteners are fully extended. Remove #7 washers and #8 screws. Remove #6 cover. 2. Remove #5 and #24 O-rings. Repeat steps for other side cover #6. The indicator (12) may now be removed. Loosen #23 nuts and #22 screws. 3. Turn the pinion shaft (17) CCW until the pistons are at the full end of travel. Disengage the pistons (2) from the pinion. (NOTE: Low pressure

air--3 to 5 P.S.I. MAXIMUM--might be required to force the pistons completely from the body.) Note the position of the pistons before removing them from the actuator body. Remove #3 bearings and #4 Orings from the pistons. Remove #13, 14 & 15 respectively from the pinion. 4. Push the pinion halfway into the bottom of the actuator. Remove #10 and #11 from the pinion. Now the pinion can be pushed completely out of the body. Remove #18, 9, and 19 from the pinion shaft. All replacement parts may now be re-assembled. BRADFORD recommends that all wear parts (repair kit) be replaced before reassembly.

REASSEMBLING STANDARD ACTUATORS IMPORTANT: Be sure that the actuator surfaces are free of grit and scratches before reassembling. 1. Apply a light film of grease to all o-rings, bearings and the pinion before replacing. 2. Put the pinion (17) back through the actuator with the flats of the pinion shaft running parallel with the body. Reverse disassembly procedure for re-assembly. 3. When reassembling the actuator, make sure that the piston racks are square to the actuator body and returned to their original orientation. (NOTE: The normal operation of all BRADFORD actuators is FAIL CLOSED. If you want to change the orientation to FAIL OPEN, rotate the racks 180º to create a reverse operation. 4. When replacing springs in a spring return actuator, ensure that the springs are replaced in their identical position in the end cap from which they were removed. (NOTE: In some circumstances, you might want to change the standard 80 pound spring set to fit your application and available air pressure. Changing the spring sets on BRADFORD actuators requires no special tools. Please refer to the spring combination torque chart in our catalog for the spring combinations that will allow you to operate with the spring set that you desire. 5. Seal the end caps with a petroleum lubricant and bolt to actuator body. 6. Check the seal of the actuator by covering seal areas (pinion, end caps) with soapy water and using low pressure air to the actuator to ensure that no bubbles are produced.
