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

In-Line Check Valve for Sprinkler, Mister & Fogger Systems

When an irrigation line shuts off, water at the low points of the run keeps draining out through the lowest heads for a period afterward, wasting water and leaving wet spots under those emitters. Netafim's check valve closes against that back-drainage, holding the line's water in place between cycles instead of letting it empty out through gravity.

This purple-pin version is rated to open and close within a 13-28 PSI range, matching it to lighter-duty sprinkler, mister, and fogger systems running in that pressure band.

Key Features & Benefits

• 13-28 PSI operating range — matches the valve's opening pressure to lighter-duty sprinkler, mister, and fogger systems.
• Stops post-cycle line drainage — prevents water from continuing to drip out of low-point emitters after the system shuts off.
• Purple pin color coding — lets growers confirm the valve's pressure range at a glance across a system using multiple valve ratings.
• In-line installation — fits directly into standard sprinkler, mister, and fogger fitting configurations.

Who Should Use This

This check valve fits growers running overhead sprinkler, mister, or fogger systems who are dealing with post-cycle drip at low points in the line, or who want to reduce water waste and localized overwatering between irrigation cycles.

Frequently Asked Questions

What problem does this check valve solve

It stops water from continuing to drain out of the lowest points on a sprinkler, mister, or fogger line after the system shuts off. Without it, those low-point emitters keep dripping for a while after each cycle ends, wasting water and overwatering that spot.

What does the 13-28 PSI rating mean

It's the pressure range within which the valve opens to allow flow during a cycle and closes to block backflow once pressure drops. Using it outside that range can mean the valve stays closed too long at startup or fails to seal fully at shutoff.

Why is this valve color-coded purple

Netafim color-codes its check valves by pressure rating so growers can identify the correct valve at a glance when a system uses more than one rating. Purple corresponds to the 13-28 PSI range.

How do I install this check valve

It installs in-line between the feeder tubing and the sprinkler, mister, or fogger head, matching standard Netafim fitting configurations for those product lines. No special tools are needed beyond a standard barb or thread connection, depending on your system.
