Watts AFV1 Check Valve, Glass-Reinforced Nylon, FNPT

The Watts AFV1 is a 1" foot valve with FNPT connections. It mounts on the suction end of a pump line to hold prime and stop water running back to the source. It features a glass-reinforced nylon body and a buna-n seat.

This 1 inch female foot valve is used at the suction end of the pump line to prevent loss of water. It is spring loaded, can be installed at any angle, and comes complete with a filter screen which can be taken off.

Features

• Ideal for agricultural, irrigation, rural and municipal, and plumbing applications
• Efficiently prevents the loss of water
• Spring-loaded, plunger style, non-return valve for unrestricted flow
• Provides easy connection with NPT threads and installs at any angle
• High grade fiberglass reinforced nylon construction offers corrosion resistance and long-lasting, reusable wear

Common Questions

Can I install it vertically?

Yes. The AFV1 is spring-loaded, so it seats at any angle — vertical, horizontal, or on an incline. Only the flow-direction arrow has to be right.

Does it come with the strainer?

Yes. The integral suction screen ships attached and lifts off without tools for cleaning, so you do not need a separate pump-suction strainer.

Is it potable rated?

No. This model is not certified lead-free, so it is not for potable-water piping — it is specified for irrigation service. Watts LF-prefixed check valves cover potable applications.
