Installation On The A120-45A & A120-60A Valves

WARNING

When installing or removing Internal Valve from tank, make sure all Product & Pressure has been removed from Nurse Tank and any Downstream Piping.

1. Remove Plate & Cap Screws from Gland Assembly. These can be discarded.
2. Install the Plate as shown. Insert the thin end of the Lever into the shaft of the Gland Assembly. Line up the hole in Lever with the hole in the Gland Assembly Shaft & insert the Cotter Pin.
3. Secure the Lever to the Gland Assembly Shaft by bending the ends of the Cotter Pin back to secure it. Verify that the Cotter Pin ends DO NOT rub against the Plate.
4. Attach the Manual Release onto the valve. Insert the New Cap Screws(2) into the Manual Release. Line up the holes on the plate with the holes on the valve. Line up the Manual Release with the holes on the plate & valve. Start threading the screws into the valve.
5. Secure the Manual Release onto the valve by tightening the Cap Screws(2) with an Allen Wrench to 25 – 30 Inch-Pounds of Torque.
6. Test the Open operation of the Manual Release. Move the Lever to the right until it stops & release it. The plunger on the Manual Release should have retracted into the Release Housing to allow movement of the lever. Once the Lever moves past the plunger it should pop out to prevent it from moving back to the Closed Position.
7. Test the Close operation of the Manual Release. Pull on the Carabiner on the end of the cable until the plunger retracts & allowing the Lever to move to the Closed Position. Release the cable. Check the position of the lever to make sure that valve is closed. Check the plunger to make sure that it has popped back out.

Operation Of The A120-45A & A120-60A Valves

To Open Valve

1. Always open the internal valve before opening any other valves in the line.
2. Move the lever to the half-open (rapid equalization) position (Operational Schematic Figure 1, View #2 – A120, A125, A15 IOM) to equalize pressure. When the main poppet clicks open, move the operating lever fully open.
3. Open other line valves slowly to avoid sudden surges which could slug the excess flow valve shut.
4. If the excess flow valve does close, close the nearest downstream valve. Move the internal valve’s operating lever back to the rapid equalizing position (outlined in step 2) and wait for the valve to click open. Then move the operating lever fully open and slowly open the downstream valve.

CAUTION

DO NOT Force open lever against NH3 Nurse Tank flow before pressure is equalized on each side of the main valve disk.
DO NOT Modify the Cable/Carabiner Assembly. Could cause Injury or Death! Only Use Squibb Taylor Replacement Parts.

To Close Valve

Pull on the Loop End of the Cable. The plunger will retract to allow the lever to move. The closing spring causes the valve to close. The operator must always be aware of where the remote closure controls are located and know how to operate the controls if an emergency requires valve closure. When finished, make a habit of closing the internal valve from the remote closure point, thus checking to see that the control actually is capable of closing the valve and operating correctly.

WARNING

Since there is strong spring force on the operating lever, avoid getting in the way of the lever as it moves to the closed position. Failure to do so could result in personal injury. Assembled Valve & Manual Release is now an Emergency Shutoff Valve for Anhydrous Ammonia (NH3) Nurse Tank.

• Test For Proper Operation @ A Minimum Of Once A Month & Daily During Field Application Periods.
• Always Test Operation Before Sending To Field For Use.

Maintenance

WARNING

ONLY PERSONNEL TRAINED IN THE PROPER PROCEDURES, CODES, STANDARDS & REGULATIONS OF THE ANHYDROUS AMMONIA INDUSTRY SHALL PERFORM MAINTENANCE ON THIS EQUIPMENT. Before starting any type of maintenance, close off the A120MAN valve(s) & remove all Anhydrous Ammonia (NH3) pressure from the Outlet of the Internal Shutoff Valve. If maintenance or repairs are to be made on the internal valve(s), refer to the Instruction Manual for the particular valve model. An A120MAN manual release that has been disassembled must be tested for proper operation before being returned to service.

CHECK ACTUATOR PERIODICALLY FOR THE FOLLOWING

1. See that the manual release is properly connected, works freely and is not worn.
2. Make sure there are no obstructions or debris to block the valve and lever from closing.
3. Make sure that both cables move freely inside the Break-Away Coupling.
