Non-Return Valve 22mm

Description

A non-return (check) valve has a spring-loaded or flap closure that opens with forward flow and shuts if the flow reverses. Our stock data does not give the body material, end connections or pressure rating, so check that it suits your pipe before fitting.

Fit it with the arrow on the body pointing in the direction of flow. Place it where it can be reached for cleaning, as grit on the seat can stop it closing properly.

Used for:

• Stopping backflow on 22 mm water lines
• Pump and tank outlets
• Geyser and solar feed lines

Sold each.
