• 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” (305 mm) 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.
*
Distances specified under the following
conditions: minimum voltage: 20 VAC, amperage:
0.12A, operating pressure: 150 psi (10,3 bar).
(if required)
(305 mm)
• 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) (,34 - 6,9 bar).
Note
: One revolution of the control dial adjusts the pressure setting approximately 10 psi (,69
bar). A minimum of 10 psi (,69 bar) 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 solely 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.
