Irritrol 100P1 Irrigation Control Valve 1 Inch Npt

Product Description

The IRRITROL 100P1 is a 1-inch NPT-threaded irrigation control valve from the Century Plus 100 Series, designed for reliable automated flow control in residential and commercial irrigation systems. Built from glass-reinforced nylon, stainless steel, and brass, it operates across a pressure range of 20 to 220 psi and features a nylon-reinforced EPDM double-beaded diaphragm for long-term sealing performance. The globe/angle configuration suits a wide range of installation orientations. Licensed irrigators and landscape contractors install this valve as part of multi-zone irrigation manifolds and inline control assemblies.

The 100P1 is suited for residential and light commercial irrigation systems where consistent zone control and high-pressure tolerance are required. The globe/angle body style allows flexible piping configurations. An externally removable stainless steel metering system supports use in recycled-water applications where debris and contamination are concerns. The valve accepts the OmniReg modular pressure regulator accessory for zones requiring downstream pressure management. Internal and external bleed ports allow manual operation and system flushing without additional tools.

Installation Notes

Installation should be performed by a licensed irrigator or qualified plumbing contractor in accordance with applicable local codes. Shut off system water supply and depressurize the line before removing or installing any valve. Apply thread sealant tape to all NPT connections and verify joint integrity before pressurizing. Do not exceed the rated operating pressure range of 20 to 220 psi.
