How To Choose Instrument Valves?

Released on Jun. 19, 2018

The Instrument Valve is a piping accessory. It is a device used to change the path section and the medium flow direction to control the flow of the transport medium. Here's how to choose the instrument valve:

1. The anti-corrosion of instrument valves is mainly due to the correct choice of materials. Although the information on corrosion protection is very rich, whether or not it is properly selected is still not easy because the problem of corrosion is complicated. The difficulty in selecting the valve body material lies in the fact that it is not possible to consider only the corrosion problem, but also the ability to withstand pressure and temperature, whether it is economically reasonable and whether the purchase is easy or not.

2. Take lining measures, such as lining lead, lining aluminum, lining engineering plastics, lining natural rubber, and various synthetic rubbers. If media conditions permit, this is a saving method.

3. When the pressure and temperature are not high, using a non-metal valve body material can often prevent corrosion. In addition, the outer surface of the needle valve valve is also subject to atmospheric corrosion, and generally steel materials are protected by brush paint.
