Can thermoplastic valves replace metal valves?

Yes, at the appropriate pressure and temperature, thermoplastic valves can replace metal valves, especially our thermoplastic ball valve AL 20-B-2014, which is designed with flange connections according to EN1092-1. The same standard used for metal valves and which allows for an easy direct change.

 

When and why you choose a thermoplastic valve

The advantages of thermoplastic valves are numerous in the right application, they are reliable for operational and personal safety, are extremely mechanically resistant and have a long service life. Their main characteristics include:

  • High resistance to chemicals and abrasion
  • Resists severe corrosion

There are metals made of special alloys that can withstand chemical and mechanical influences, but are usually offered at a much higher price than thermoplastics such as PPGF and PVDF. Contrary to popular belief, thermoplastic valves offer higher abrasion resistance than metal valves in chemical applications.
