Rain Bird CPF075 In-Line Automatic Sprinkler Valve with Flow Control – 3/4-inch Female x Female

Smart control for consistent, efficient irrigation

The Rain Bird CPF075 is a compact, in-line sprinkler valve designed for residential and light commercial use. With a 3/4-inch female inlet and outlet, this valve sits below ground, out of sight, yet plays a pivotal role in shaping how each zone receives water. A user-friendly, top-mounted flow control knob helps tailor flow to the destination area, supporting uniform coverage and reducing overspray.

Key benefits and practical use cases

• Flow control for tailored zones: adjust the flow to reduce misting and improve coverage where you want it most.
• Below-ground design: discreet installation keeps outdoor spaces tidy and child-safe while protecting the valve from weather and impact.
• Manual bleed and automatic operation: the valve can be managed manually or left to operate with your 24 V AC controller.
• Reverse-flow design: minimizes diaphragm stress, contributing to dependable operation and reduced risk of leakage in adverse conditions.
• Efficient solenoid and durable diaphragm: energy-efficient, low-power solenoid with a Buna-N diaphragm designed for harsh water environments.
• Broad compatibility: works with Rain Bird spray heads, rotors, and impact heads, making it a versatile choice for mixed irrigation setups.

Real-world scenarios and how it helps

Imagine a lawn with uneven terrain or multiple plant beds that require different watering needs. The CPF075 lets you fine-tune flow per zone, helping to achieve more uniform coverage without excessive mist. In areas with hard or mineral-rich water, the Buna-N diaphragm is designed to maintain reliable performance. The valve’s reverse-flow design adds a layer of protection against unintended flooding caused by diaphragm issues, which can be a concern in busy irrigation systems.

Installation, compatibility, and best practices

This valve is intended for below-ground installation downstream from the main line, typically in a valve box. It’s designed for 24-volt AC irrigation controllers and is compatible with various Rain Bird devices, including spray heads and rotors. City codes may require a backflow prevention device, so check local regulations before installation. Always flush the system manually using the external bleed screw after installation and before startup to clear dirt and debris and promote a smooth first run.

Durability and quality you can rely on

Crafted from high-impact materials, the CPF075 emphasizes longevity in outdoor environments. The encapsulated solenoid is designed to draw minimal power while delivering dependable valve operation, and the captured plunger helps maintain alignment over time. This combination supports long-term, low-maintenance irrigation performance.
