Product information "Grafi-sil valve balls"

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.

We offer you a sample set with 2 balls of each size - with a price advantage of 20% !!!

2x4mm / 2x5mm / 2x6mm / 2x8mm

Whoever has used Grafi-sil balls does not take anything else!

!!! Grafi-sil valve balls are also used in machine and plant construction !!!

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.

Pressure springs stainless steel

Our pressure springs made of stainless steel can be ordered in various sizes and diameters. You get the springs in packing units of 5pcs. Since the dimensions of the compression springs are particularly small, they are ideally suited for use in model construction. We use the springs in various models. For example, as a valve spring in the internal combustion engine "Karl". We have also used the pressure springs as a pressure spring for a flame damper slide. In addition, the compression springs are also suitable as twist protection for nozzle needles of model building carburetors or for the needles of droplets. All springs are made of stainless 1.4310 stainless steel spring steel wire. In addition, we offer you a pressure spring probeset in which of each spring 2 pieces are included. With the Probeset, you are prepared for many applications in model construction.

Tip

Silberhartlotstangen mit niedrigem Schmelzpunkt zum Löten im Modellbau

high-alloyed silver solder 1mm / 1,5mm

We have silver braided bars with a silver content of 55% (L-Ag55) with a length of 500mm. Because of the relatively low melting point of this silver braze, the model builder in the field of technical model building is almost exclusively concerned. The working temperature of this hard solder is 630 ° C. The silver as an alloying component in the solder does not only reduce the working temperature, but also improves the flow properties. Furthermore, silver has the positive property of combining well with other metals. For brazing brass and steel, silver solder flux is essential. The low working temperature of the silver solder bars allows the thermal load to be as low as possible for the processed material. It is important not to heat the workpieces too much, especially in the case of brass. In combination with our silver solder flux you achieve with these silver solder always optimal results. The silver braided bars can be purchased from us in the shop in 2 different diameters. For fine soldering as it often happens in technical model construction we recommend the 1mm rods. The 1mm silver braided bars are easy to carry with the hand and can be easily melted with small burners. For larger parts we prefer the 1.5 mm silver solder bars. With these rods you get faster material to the soldering point if needed. What can be brazed?The following materials can be combined with silver solder: brass, copper, gunmetal, gray cast iron, rusting steels and stainless steel. A combination of the materials among each other is easily possible with this silver braze solder. If the material is not known to you, it is always recommended to solder a piece to the sample beforehand. This allows you to determine whether the materials can be combined with the silver braze.Instructions Brazing with silver solder If you have never worked on silver solder and you are not sure how the exact solder brazing procedure is with silver solder, we can help you before you buy the silver solder. We have created a guide for you in our Bengs Modellbaumagazin on the topic "Brazing with silver solder". Here you can find out what you need and have to consider if you want to solder 2 components with silver solder. Tip: Flux residues and discoloration of the material can be optimally eliminated with our satin brushes or abrasive fleece!Characteristics of the silver solder bars500 mm long. 1mm or 1.5mm diameter Silver solder bars L-Ag55 (55% silver) Working temperature 630 ° C Bengs Modellbau has used this silver solder bars for years.
