Rain Bird CPF100 In-Line Automatic Sprinkler Valve with Flow Control - 1-inch Threaded

Overview

The Rain Bird CPF100 is an in-line sprinkler valve designed for residential and light commercial irrigation. With a 1-inch female inlet and outlet, it offers precise flow control to help you tailor zone coverage without overspray. Its compact, below-ground footprint keeps irrigation hardware hidden and protected, while remaining easy to service from a valve box.

Built for steady performance, the CPF100 combines a reverse-flow design with an energy-efficient solenoid and a Buna-N diaphragm. This configuration supports reliable operation in variable water conditions and reduces energy draw, giving you efficient control over your watering schedule when paired with a standard 24-volt irrigation timer or controller.

Key Benefits

• Residential and light commercial grade valve with flow control to minimize misting and optimize coverage
• Top-mounted, easy-turn flow control knob for zone-by-zone adjustments
• Reverse-flow design helps prevent flooding if the diaphragm encounters an issue
• Energy-efficient, low-power encapsulated solenoid with captured plunger
• Buna-N diaphragm provides reliable performance in challenging water conditions
• Compatible with Rain Bird spray heads, rotors, and other irrigation devices

Below-Ground Reliability and Use

Designed to be installed out of sight, the CPF100 sits below ground in a valve box, protecting it from dirt and damage while keeping the landscape tidy. The valve can operate automatically or be actuated manually using the bleed screw for testing or emergency operation. A well-flushed system at startup is recommended to remove debris and ensure smooth performance.

• Install downstream from the main line and in line with local backflow requirements
• Flush the system manually through the external bleed screw before first use
• Use with 24V irrigation timers/controllers for automated scheduling
• Remember that inline valves do not protect against backflow by themselves; comply with local codes

Whether you are watering a lawn, garden beds, or mixed-use landscapes, the CPF100 offers a practical balance of control, durability, and ease of use. It is a solid option for zones that benefit from adjustable flow without the need for bulky on-site valves.
