Netafim™ Check Valve for Sprinklers, Misters & Foggers - 13-28 PSI - Purple Pin

Backflow Prevention Purpose-Built for Overhead Irrigation Devices

The Netafim™ Check Valve for Sprinklers, Misters & Foggers prevents backflow in compatible overhead irrigation devices, protecting system integrity and ensuring consistent, controlled water movement across the full irrigation layout. Identified by its purple pin color code, this check valve opens at 28 PSI and closes at 13 PSI — providing reliable backflow prevention within the pressure range typical of misting and overhead irrigation applications. Engineered by Netafim for integration into their sprinkler, mister, and fogger product lines.

Key Features & Benefits

• Backflow prevention — stops reverse water flow through irrigation devices, preventing contamination and system pressure loss between cycles.
• Purple pin color code — easy identification in the field; distinguishes this check valve from other Netafim pressure-compensating and flow control devices.
• Opens at 28 PSI / closes at 13 PSI — pressure range engineered for overhead irrigation applications with sprinklers, misters, and foggers.
• Compatible with sprinklers, misters, and foggers — designed to integrate directly with Netafim's overhead irrigation device lineup.
• Supports system reliability — consistent check valve performance maintains uniform delivery across all emission points in the system.

Who Should Use This

Greenhouse operators, nursery growers, and irrigation professionals running Netafim sprinkler, mister, or fogger systems who need backflow prevention at the emitter level.

Compatibility

For use with compatible Netafim sprinklers, misters, and foggers. Opens at 28 PSI, closes at 13 PSI. Purple pin. Product code 63000-003005 / 0340017-B.

Frequently Asked Questions

What does the purple pin color code mean?

Netafim uses color-coded pins to distinguish different pressure and flow specifications across their check valve and pressure-compensating device range. Purple indicates this specific 13-28 PSI check valve for sprinklers, misters, and foggers.

Does this check valve also regulate pressure?

This is a check valve only — it prevents backflow but does not regulate or compensate for supply pressure variation. Use a pressure-compensating emitter for pressure regulation.

At what pressure does this valve open?

The valve opens at 28 PSI and closes when pressure drops to 13 PSI, preventing drainage and backflow through the emitter after each irrigation cycle.

Can I use this check valve with non-Netafim sprinklers or foggers?

This valve is designed for compatible Netafim devices. Use with non-Netafim emitters should be verified against thread size and fitting compatibility before installation.
