What is the maximum temperature that an Air Valve can withstand?

We recommend working under 150°C (302°F). Above that temperature, steel starts dilatation, so the resort introduced on the Air Valve would lose efficiency. If so, the plastic material could go in and the Air Valve would be damaged.

What is the maximum air pressure that can be used?

10Bars (145 psi).

Can I remove the valve from the tool?

Yes, on our catalogo page we indicate the size of the hole (E dimension) to be made before installing, the valve can then be removed using the appropiate ejector.
On the smaller diametres (5 & 6) extra care needs to be taken to remove the part slowly, knocking softly to avoid damage to the internal mechanisms.

Is there any limitation on the position of the valves in the mold?

The valve should not be installed below the injection point. In that position the high temperatures and pressure could negatively influence the valve components and decrease their lifetime.
