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 Internal Bleed Handle counterclockwise to the ON position.
Note: EZReg operation is bypassed when the valve is manually actuated
using the External Bleed Cap.
• 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.
