Grafi-sil valve balls

Grafi-sil valve balls are made of a special silicone rubber. The valve balls ensure 100% tightness in steam model construction with their check valves, feed water pumps and injectors, even when the ball sockets are removed or dirty. They can be used in steam, water and oil pipes and are absolutely noise-free.

The following valve ball diameters are available:

• 4mm Grafi-sil valve balls
• 5mm Grafi-sil valve balls
• 6mm Grafi-sil valve balls
• 8mm Grafi-sil valve balls
• 10mm Grafi-sil valve balls
• 12.7mm Grafi-sil valve balls
• 15,2mm Grafi-sil valve balls

You can of course also retrofit the Grafi-sil balls into your existing components. The maximum ball diameter must always be selected. Sufficient is already 0.3mm distance between ball and armature diameter. The graphi-sil spheres can be used up to a temperature of 400 ° C. We use the Grafi-sil spheres, among other things, as outlet valve balls for our flame eaters.
