Irritrol 100 User Manual
100 Series Century Plus Valves
Installation Instruction
Introduction
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.
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. The use of clean aggregate in
the bottom of the box, and locating the valve box away from
structures, potential hardscaping features (such as sidewalks)
and large planting locations is recommended. Additionally, valve
box locations generally should be in shrub beds and at right
angles to structure locations. If the 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.

For optimum performance when designing a system, be sure to calculate total friction loss to ensure sufcient downstream pressure.
For optimum regulation performance, size regulating valves toward the higher ow ranges.

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 ow 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 ow and pressure to valve outlet.
By turning the control handle clockwise, the ow 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 (ush mode)
The external manual bleed knob, located on top of the ow
control handle, is used for system ushing. Turning this knob
counterclockwise allows water in the diaphragm chamber to
vent to atmosphere, creating maximum opening power and
debris ushing 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.
