Frequently Asked Questions - 102P3 Irritrol

What is the maximum operating pressure for the Irritrol 102P3 valve?

The maximum operating pressure is 220 PSI.

Can the 102P3 be used with dirty water?

Yes, the 100S 'Scrubber' version features a continuous scrubbing turbine that actively cleans the metering device for reliable operation in dirty water applications.

What voltage does the solenoid require?

The solenoid operates on 24 VAC. Inrush current is 0.40-0.50 amps and holding current is 0.20-0.30 amps.

How do I manually operate the valve?

Turn the internal bleed knob (under the solenoid) counterclockwise to open the valve manually. Turn clockwise to close.

How do I flush the valve to remove debris?

Turn the external manual bleed knob on top of the flow control handle counterclockwise. This vents water to atmosphere, fully opening the valve for maximum flushing.

What are the dimensions of the 1-inch model?

The 1-inch globe/angle model measures 6 3/4 inches high and 3 5/8 inches wide.

What is the flow range of the valve?

The flow range is 5 to 300 GPM depending on size and configuration.

Can the valve be installed in any orientation?

Yes, the valve can be installed at any angle without affecting operation.

What type of pipe sealant should I use?

Use only PTFE tape or pipe thread sealant. Do not use pipe dope as it can damage the threads.

How do I adjust the flow rate?

Turn the flow control handle clockwise to reduce flow down to zero. Turn counterclockwise to increase flow.

Installation Instruction

Introduction

100 Series Valve

Built on proven technologies and components, the Irritrol 100 Series valves are tough, have excellent performance, and are extremely reliable. A self-cleaning metering system and 220 PSI rating assures years of trouble-free performance.

100S Series "Scrubber" Valve

Constructed of heavy-duty, glass-reinforced nylon, high grade stainless steel, brass and EPDM rubber materials, the 100 Series scrubber valves resist clogging. The patent-pending continuous scrubbing mechanism actively fights dirt, algae and other particles from disrupting the functionality of the valve. The 100 Series scrubber valves are true dirty water irrigation valves, able to handle the harsh chemicals found in dirty water systems, such as chlorines, chloramines and water treated with ozones.

Installation Recommendations

• In commercial installations, it is advantageous to install the valves in a valve box. This enables the valve to be easily located, accessed, and maintained.
• Partially fill the bottom of the valve box with clean aggregate to facilitate drainage.
• Locate the valve box away from structures, hardscape features (such as sidewalks), and large planting locations.
• Locate the valve box in shrub beds and at right angles to structure locations.
• If valves are installed below grade without a valve box, access to the top of the valve should be provided by using a section of 4" PVC pipe and a valve cover installed directly over each valve.

100S Series "Scrubber" Valve

• All the great features of the 100 Series valve.
• Continuous scrubbing turbine actively cleans the metering device for consistent valve operation in dirty water applications.

Installation Guidelines

Using pipe dope on valve connections can cause thread damage and failure of the valve body.

Use only PTFE tape or pipe thread sealant.

• Note the flow direction arrows on the bonnet or body and install accordingly.
• The valve can be installed at any angle without affecting operation.

• The valve body plug and o-ring must be properly installed in the unused inlet.

• Use direct-burial wire, utilizing different color codes for each station control wire and one color for the common wire to all valves.

• Waterproof wire splice connectors are absolutely essential for proper electric control system operation. Follow the installation instructions provided with the connectors for optimum waterproof splice protection.
• Leaving a wire expansion loop at each valve location on long-run wire lengths is recommended.

Valve Operation

Flow Control

Flow control reduces the flow and pressure to valve outlet. By turning the control handle clockwise, the flow will be gradually reduced to zero.

Internal Manual Bleed Knob

The internal manual bleed system is used to manually operate the valve. Turning the internal bleed knob (located beneath the solenoid) counterclockwise allows water to bleed downstream from the diaphragm chamber. Internal

pressure is relieved from the top of the diaphragm, allowing the valve to open. Turning the bleed knob clockwise until tight shuts off the discharge enabling pressure to build within the diaphragm chamber, causing the valve to close.

External Manual Bleed Knob (flush mode)

The external manual bleed knob, located on top of the flow control handle, is used for system flushing. Turning this knob counterclockwise allows water in the diaphragm chamber to vent to atmosphere, creating maximum opening power and debris flushing action. This operation bypasses the regulator (if installed) and opens the valve fully, regardless of regulator setting. In addition, the metering rod (attached to the external bleed knob) can be easily removed for cleaning as necessary.

100S Scrubber Operation

Continuous scrubbing turbine actively cleans the metering device for consistent valve operation in dirty water applications.
