Sealability and strength property are the most basic and most important characters for all valves. The sealing of a valve can be separated into internal seal and external seal. The front one means the sealing between valve clack and seat. The latter one means the sealing between the moving part of the valve stem and bonnet, body and bonnet, body and connection part. When the valve is used, it should be not only good in sealability but also be safe.
Another way of cheating customers - to use for the manufacture of shells cheaper metal - zinc. This is also the risk of counterfeiting. valve of zinc has increased brittle and may crack on the mechanical and hydraulic influences. There are ball valves, made from silumin (aluminum alloy). Their reliability is still lower. Savings metal induces dishonest manufacturers to produce the body taps with wall thickness from 1 to 0,5 mm. This is extremely reduces their reliability. (For comparison, the standard valves manufacturers Matca-Norca have a wall thickness of 2 mm).
Swagelok Valves, as with all Swagelok products, are thoroughly tested, and the customer is assured that they will perform reliably, meet expectations of quality and are backed by the Swagelok Limited Lifetime guarantee. Valves are devices which are designed to open, close, or partially obstruct passageways in pipers, and in this way they regulate the flow of fluids and gasses. Valves have application over many different areas of many industries - this means they come in numerous designs and materials depending on the specifications they must meet. For this reason Swagelok produces top of the range Process, Instrumentation and Sanitary Valves, in a range of materials and end connections. Where necessary, Swagelok can manufacture or configure Valves to the special needs of a client's system requirements.
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:
The determining factor of this valve in every aspect of usage, no matter whether the processing involves liquids, fluids or heavy duty and abrasive materials, is the elastomer sleeve. It is the controlling factor of any Air Pinch Valve, not only in respect of usual high performances, but for total versatility in operating in adverse conditions and environments. However, although valve sizing is of a critical priority, the selection of the correct elastomer sleeve for an operation is a maximum priority.
In standard valves, when it is given a command to open to a certain point, there is no feedback to verify that the valve has opened to that position. With a valve positioner, the command is given and the valve positioner reads the opening, verifying the position and readjusting until it gets it to the exact position needed. This allows for great precision in the adjustment.
