Installation and Operating Instructions

Introduction

The P220G Series provides a full family of plastic valves are designed specifically to meet the challenging needs of today’s golf course irrigation systems. Featuring precision pressure

egulation, the P220G Series valve delivers the optimum pressure and flow to every sprinkler

r on the zone, ensuring maximum uniformity of the water to the turf.

The EZ-Reg pressure regulating system, a standard feature on all P220G valves, provides consistant operating pressure. From low-pressure/flow applications of drip irrigation, to the high-pressure/flow requirements of high-volume sprinklers, the EZ-Reg adjusts easily with the micro-adjust dial and indicator, to provided constant downstream pressure 5–100 psi.

Also standard on the P220G series, is the heavy-duty SpikeGuard™ solenoid. Providing 20,000-volt lightning protection – the SpikeGuard solenoid has proven to minimize down time and service costs, even in the severe lightning-prone regions.

Note: The P220G valve should be installed below grade in a valve box or vault to provide service access and vandal resistance. The valve installation site should be readily accessible by grounds maintenance personnel and well clear of hardscape features, cart paths and foot traffic areas.

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.

Typical Installation Detail

Common Wire Gauge Size

Note: Values indicate maximum. one-way distance ( in feet) between controller

and valve solenoid under the followig conditions: minimum voltage - 20 VAC, maximum amperage - 0.12A and operating pressure - 150 psi.

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).

Flow Control Handle

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.
