Thanks to the reliability and durability of ball valves the market demand is constantly growing. However, the other side of the medal is that high demand always generates the production of poor quality and fake products, the use of which puts in jeopardy the operation of the entire complex. And this is where a logical question arises – how to distinguish a fake from the original?
The demand for ball valves increases due to the excellence of their design, strict control of the chemical composition of materials and manufacturing technology. A counterfeit manufacturers ignore all these factors and, under the guise of well-known brands, creating something that looks like the original.
Production materials matter
Ball valves, or at least the valve body must be made of brass, which is regulated by the composition corresponds to the national standard. As a rule, such standards provide a zinc content of 60%, lead content in the range 0.8-1.9%, and 57-60% of copper. Fake valves are typically made of non-ferrous scrap, and nobody actually cares about the percentage of metals. As a result, for example, the lead content can be up to 5 – 7%, and it is harmful to human health.
Another type of forgery is the use of a cheaper material for body – zinc. The use of such equipment poses certain risks. Due to the increased fragility it can crack during mechanical action or differential pressure. Add to this the impact of chlorine water on the zinc (a solution which is formed from chlorine and zinc – zinc chloride is carcinogenic), whereby products become thinner and less reliable. There are valves made of aluminum and their body is quite thin – 0.5 – 1mm, while reputable manufacturers stick to wall thickness of no less than 2 mm.
But this is not limited to ways to save at forging cranes. Leading manufacturers of ball valves made by hot forging or hot pressing. In order to save counterfeits produce castings. Therefore, they differ from the original products uneven surface of the housing, the influx, and the material has a heterogeneous structure whereby poor reliability. Ball valves, too fake, not producing them in brass and stainless steel, so they rust and leak disappears crane. A crane branded manufacturers pay great attention to the rotary valve. Brass balls exposed diamond grinding, and then they are coated with nickel or chromium. As a result, the ball gets a perfect mirror surface. We forged a spherical surface dull and rough.
Experts say that there are fake, where construction cranes modified to reduce the cost of production at the expense of quality.
It is best to buy a ball valve at the official distributors of these firms. Thus, for example, if you are looking to purchase Orseal products, you should better order a shipping through sales representatives, or, as an option, you may want to look Orseal ball valves and industrial ball valves online. If it is not possible, you can call the official distributor and ask whether the reseller you are going to deal with is on the list. Manufacturers on Internet sites often place drawings of the products and put descriptions, so by checking the original labels, the size, weight and dimensions of this or that product you can understand whether it is a genuine quality product or a fake one.
