1. See that the manual release is properly connected, works freely and is not worn.
2. Make sure there are no obstrucons or debris to block the valve and lever from closing.
3. Make sure that both cables move freely inside the Break-Away Coupling.
Open
Closed
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 nished, 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 operang correctly.
1. Always open the internal valve before opening any other valves in the line.
2. Move the lever to the half-open (rapid equalizaon) posion (Operaonal Schemac Figure 1, View #2 - A120,
A125, A15 IOM) to equalize pressure. When the main poppet clicks open, move the operang lever fully open.
3. Open other line valves slowly to avoid sudden surges which could slug the excess ow valve shut.
4. If the excess ow valve does close, close the nearest downstream valve. Move the internal valve’s operang
lever back to the rapid equalizing posion (outlined in step 2) and wait for the valve to click open. Then move
the operang lever fully open and slowly open the downstream valve.
