Brand: Irritrol SKU: 205S
Product Overview
The Irritrol 205S is a 1-inch slip-connection irrigation valve for residential sprinkler and landscape watering systems. It is the non-flow-control slip model in the 205 Series, making it a direct choice when the piping uses solvent-weld PVC connections and local throttling is not required. The compact valve body is designed for potable-water and dirty-water applications and can serve spray, rotor, bubbler, or properly designed drip zones.
The 205S uses heavy-duty, corrosion- and UV-resistant PVC construction with stainless-steel components and a nylon-reinforced Buna-N diaphragm. Irritrol rates the 205 Series for approximately 0.25 to 30 GPM and 10 to 150 PSI. A manual bleed supports field testing and service, while the standard 24 VAC solenoid connects to a compatible irrigation controller. Because this model does not include a flow-control stem, zone balancing must be handled through system design or another compatible component.
This valve is frequently used to replace matching 1-inch slip valves in established Irritrol, Richdel, and Hardie installations. Always confirm body style, connection type, and available valve-box space before ordering.

Compatibility and Installation Notes
Use with compatible 1-inch PVC pipe and the correct primer and solvent cement. Follow pipe-manufacturer cure times before pressurizing. Install with the valve flow arrow aligned to water movement, flush the lateral piping, and provide access for future diaphragm or solenoid service. A compatible 24 VAC irrigation controller is required for automatic operation.
Frequently Asked Questions
Does the 205S include flow control?
No. Choose the 205SF slip model when flow control is required.
Are the connections threaded?
No. The 205S uses 1-inch slip sockets for solvent-weld PVC piping.
Can it replace an older Richdel valve?
It may replace compatible 1-inch slip installations, but confirm the connection style and valve dimensions before ordering.
