A few more examples from Swagelok's incredibly large catalogue of Valves for every need include Bellows-seated Valves, made with 316L Stainless Steel constructions, with Swagelok tube fitting, weld, and VCR ® and VCO fitting ® ends. Other features include full pressure rating in either flow direction for system versatility, and that the Valves are easily purged to maintain clean operation. Another type of Valve manufactured by Swagelok is the Check Valve which allows fluid to flow in one direction only.
We have come across pipelines all around that efficiently transport vast amounts of liquids and gases (collectively called as fluids). But they need a regulating body to decide the amount of the flow and to start and stop the flow for their efficient working. Here, valves come into picture and are the regulating body that control the flow rate and act as a switch to start and stop the flow.
Generally speaking, the valve for low-pressure and non-corrosive fluid is made of cast iron or cast copper. The high or middle-pressure is made of cast steel or forged steel. As for the valve used in the high-temperature or high-pressure, it will select the alloyed steel as the main material. Beside, stainless steel, plastics, chlorimet such as titanium alloy or lead alloy are applicable for the main materials of the valve used for the corrosive fluid.
My goal is either a fake - under cover, used well-known brand, at minimal cost to create an external object like a fake. First, what saves the underground businessmen, it is - raw. Shells taps and ball valves shall be manufactured from special grades of brass, the chemical composition of which in USA are regulated by GOST and abroad - national standards. These standards include the copper content 57-60%, zinc - up to 40%, lead within 0,8-2,2%. (Lead is required to make the brass surface hardness). Illegal vendors typically use non-ferrous metals, the content of impurities which are not controlled. As a result, manufactured valves, the percentage of lead content in which, studies show that reaches 5-7%. It is well known that an excess of lead in water is very harmful to health.
A gate valve is one of the commonly used valves to open and close the flow of liquid from straight line medium. This can be found in a number of places. An instance would be in irrigation as well as used in different chemical plants to regulate the path of various types of fluids.
The general consumer is difficult to distinguish a fake ball valve from the original. Here are some simple tips to help in some cases this can be done. If you can not buy products directly from the distributor, you can contact him by phone and to clarify whether it is an official supplier of your seller. All known manufacturers of ball valves have their own web pages. Of these, you can learn about the mandatory labeling of attributes of products, design features, etc. Some manufacturers place the working drawings of its products. When you're all aware of the labeling, dimensions, weight and other attributes of your product, you will easily determine its authenticity. If such arrangements you have no time, you can use some practical advice:
