Grey 3.5 Bar Safety Valve for Foam Pro 12

The IK Foam Pro 12 safety valve (IK 1291, code 82676806) is the grey pressure relief valve that opens at 3.5 bar (50 PSI). IK's technical team specifies this grey valve for the IK Foam Pro 12 sprayer and the Multi Pro 12+, both of which run at 3.5 bar. It screws into the tank and vents air once the pressure reaches its rating, so the sprayer can't be pumped past the level IK designed it for. A grey valve that releases well below 50 PSI has usually been weakened by acid: IK notes that acidic products can make the spring lose tension.

The valve looks almost identical to the white IK 1255 Multi Pro safety valve, which opens at 2.5 bar (36 PSI) and belongs on the standard Multi Pro 12. Fitting the white valve to a Foam Pro 12 or a Multi Pro 12+ caps the tank at 36 PSI and weakens the foam, so check the color before you order. Pair a valve swap with the IK Foam Pro 12 nozzle kit if the sprayer is due for service.

What Makes it Great:

🎯 Opens at 3.5 Bar (50 PSI): The release point matches the working pressure IK designed the Foam Pro 12 and Multi Pro 12+ around, within a small factory tolerance.

🎨 Grey Body for Quick ID: IK colors this valve grey and the 2.5 bar version white, so the correct valve is easy to confirm at a glance.

🛡️ Over-Pressure Protection: The valve vents excess air before the tank exceeds its rating, protecting the tank, seals, and operator.

🏭 Genuine IK Part: This is IK's own 82676806 valve, the same part installed on new Foam Pro 12 sprayers.

Frequently Asked Questions

What pressure does the IK Foam Pro 12 safety valve release at?

3.5 bar, or 50 PSI, allowing for a small tolerance. The same grey valve and rating apply to the Multi Pro 12+.

What is the difference between the grey and white IK safety valves?

The grey 1291 opens at 3.5 bar (50 PSI) for the Foam Pro 12 and Multi Pro 12+. The white 1255 opens at 2.5 bar (36 PSI) for the standard Multi Pro 12. They look alike, so match the color to your sprayer.

Why does my IK sprayer safety valve release too early?

Check the color first: a white 2.5 bar valve on a sprayer that needs grey will vent at 36 PSI. If the color is right, acidic products may have weakened the spring, and IK recommends replacing the valve.
