Industrial factories dealing with any kind of liquid or gas need quality fixtures that regulate the flow of these substances. This equipment includes taps, gate valves, valves, valves and fittings.
Valves are used to shut off the flow and belong to throttling devices, which are widely presented at http://www.akv -ia.de/page-articles.html?n=3 , where the best offers from European manufacturers are concentrated. Pipe fittings are used not only in industry, but also for household needs. There are certain rules by which such devices are manufactured. There are regulated standards of standardization, thanks to which products of this kind have certain unified properties of applicability. The material of manufacture of the locking equipment depends on the industry in which they will be used. Basically, for the production of valves, alloyed steels or non-ferrous metals are used.
Each shut-off and /or control device must have the following markings:
- What material is the product made of
- Flow direction
- Dn (conditional pass)
- Average working pressure, MPa and temperature
- Brand of the manufacturer
For valves with a passage diameter of more than 20 mm, the product passport must contain the following information:
- Mechanical properties
- Chemical composition
- OTK check mark
- Operating modes
- Modes of heat treatment
Such equipment should be ordered from trusted manufacturers with an impeccable reputation, since low-quality equipment can lead to very serious consequences. Starting from a small malfunction and ending with the failure of complex nodes.
