Irritrol – 205 Series Valves

Brand: Irritrol    SKUs: 205SF, 205T, 205TF

Product Overview

The Irritrol 205 Series is a group of 1-inch residential irrigation valves offered here in slip and female NPT configurations, with or without flow control. The series is designed for potable-water and dirty-water applications where a compact, serviceable valve is needed for sprinkler, spray, rotor, or drip zones. This listing includes the 205SF slip valve with flow control, the 205T threaded valve without flow control, and the 205TF threaded valve with flow control.

All three models use heavy-duty, corrosion- and UV-resistant PVC construction with stainless-steel components and a nylon-reinforced Buna-N diaphragm. The high-flow, low-friction-loss body is rated for approximately 0.25 to 30 GPM and 10 to 150 PSI. A manual bleed allows the valve to be opened for testing or service without activating the irrigation controller. Models ending in “F” include a flow-control stem for zone balancing and manual shutoff; the 205T does not include that feature.

Each valve is supplied with a standard 24 VAC solenoid for use with compatible irrigation controllers. Because connection style and flow-control configuration cannot be changed after installation without replacing components, verify the exact variant before ordering.

Compatibility and Installation Notes

Match the connection type to the existing pipe before ordering. Slip models require compatible solvent-weld PVC installation, while threaded models require matching male NPT fittings. Install with the flow arrow aligned to water movement, flush the line before final operation, and provide valve-box access for service. Use with a compatible 24 VAC controller.
