nstallation Guidelines

• Note the flow direction arrow in the side of the valve body

and install accordingly.

• The valve can be installed at any angle without affecting

operation.

• Use direct-burial irrigation control wire for connection from

the controller to valves.

• Leave a 12" wire expansion loop at each valve location on

long-run wire lengths.

• Waterproof wire splice connectors are absolutely essential

for proper electric control system operation. Follow the

installation instructions provided by the connector

manufacturer for optimum performance.

Valve Adjustment Procedures

• Close the valve by turning the Flow Control Handle fully clockwise, just until

resistance is felt - do not overtighten!

• Remove the EZReg dial protective cover (if installed). Turn the control dial

until the pointer indicates the desired downstream pressure (5 to 100 psi).

Note: One revolution of the control dial adjusts the pressure setting

approximately 10 psi. A minimum of 10 psi pressure differential between

the valve inlet and outlet is required for proper EZReg operation.

• Pressurize the main supply line to the valve. Confirm that all pipe connections

are properly sealed.

• Actuate the valve either electrically at the controller, or manually by turning

the Manual Bleed knob counterclockwise sloely until the valve opens.

• Turn the Flow Control Handle slowly counterclockwise to adjust sprinkler

operation.

• To confirm outlet pressure, remove the poppet valve cap, located directly

below the EZReg. Attach a water-pressure test gauge to the poppet valve

for a direct reading. Adjust pressure as preferred.

Important: The EZReg assembly can be removed for service while

the valve is pressurized. However, the valve must not be operated with

the EZReg assembly removed.

• Close Manual Bleed knob (if necessary) to close valve.
