• Three Nozzle Sizes - Multiple nozzle sizes provide 45.1 to 82.2 GPM
flow and produce watering radii from 78 to 108 feet.
• Long Life Gear Drive - Gear drive mechanism is vacuum-packed with
lubricant and isolated from water stream for long, trouble-free life.
• Valve-In-Head Models - Permits head-by-head control to customize
turf watering for various topography and soil conditions. Multi-cycle for
wind or runoff problems, frost control and dew removal without low-head
drainage. Available for hydraulic normally open or 24 Volt electric
systems.
• Sprinkler Operating Mode - Electric valve-in-head models have three
modes of operation; AUTO, ON and OFF. Mode is set using a selector
tool inserted through the sprinkler body flange.
• Built-in Check Valve - Check-o-matic sprinklers utilize a check valve in
the sprinkler base to prevent seepage from low area heads after valve
closure. Check valve will hold up to 35 feet of elevation differential.
• Two-Speed / 60°-120° Models - Provides for more even precipitation.
Runs at half speed in non-overlapping areas.
• Two-Speed / 180° Models - Provides for more even precipitation
where only a selected area is covered by an overlap, such as is found on
greens. Runs at half speed in non-overlapping areas.
• Serviceability - All internal parts of the sprinkler are accessible through
the top of the sprinkler body.

    Another important function of the pilot valve is to regulate the water pressure to the sprinkler nozzle. Pressure regulation compensates for large variations within the system and maintains a constant pressure for optimum sprinkler operation. The 690 series pilot valve is factory set to regulate at 80 or 100 PSI depending on sprinkler model.
