Manual Operation
Note: The valve can be manually operated using the external or internal bleed
controls. Refer to Figure 3.
Bleed Screw (external bleed): Turn the bleed screw counterclockwise one full
turn or until water begins discharging past the bleed screw threads.
Note: Removing the bleed screw is not required for manual operation, but can be
removed to help flush debris from the upper diaphragm area.
To close the valve, turn the bleed screw clockwise until it stops. Do not over-tighten!
Bleed Handle (internal bleed): To open the valve, move the bleed handle coun-
terclockwise to the stop. The valve will open as discharge water is routed internally
downstream. To close the valve, move the handle clockwise until resistance is felt.
Do not over-tighten!
Flow Control Adjustment
The valve is set for maximum flow at the factory. If flow adjustment is required, use
the following procedure:
1. While the valve is operating, use a small screwdriver to turn the flow control
screw clockwise to decrease flow or counterclockwise to increase flow.
Note: The flow control screw requires approximately seven turns to adjust from maximum to minimum flow.
CAUTION: Do not use the flow control to shut off the valve. Do not force the flow control screw past the end of normal adjust-
ment travel. Damage to the flow control components can occur.
Maintenance Procedure
The EZ-Flo Plus valve series features a threaded cap nut which enables the valve
to be easily disassembled for maintenance. See Figure 4 for the following proce-
dure.
1. Shut off the water supply and bleed pressure from the valve using the bleed screw.
2. Turn the cap nut (1) counterclockwise to remove.
3. Remove the cover assembly (2) by gripping the solenoid and gently rocking it
back and forth until the assembly is loose and lifts off.
4. Remove the spring (3), diaphragm (4), and divider (5).
5. Turn the anti-siphon cap (7) counterclockwise to remove.
6. Remove the stem assembly (8).
7. Inspect the valve body and internal parts for wear and debris.
8. Clean and reinstall parts into the valve body in reverse order.
Winterization
When winterizing the sprinkler system using compressed air, operate each valve
manually from the timer or at the valve for a minimum of one minute, enabling each
valve to be thoroughly drained.
