Are plastic valves a good alternative to metal, lined or ceramic valves?

Many consider plastic valves because they are much cheaper, but let us tell you this: there are also really inexpensive metallic valves to use on your installation. So the price issue should not be your main reason.

Let's take a closer look at the more important benefits of plastic valves.

So when should you really consider plastic valves?

First when the environment you have to place the valves in is really harsh or corrosive: sulfuric acid, sodium hydroxide, sea water – a thermoplastic valve can be a good alternative to something like a titanium, Hastelloy or lined valve. In seawater for example, a plastic butterfly valve will last longer and will be subject to less corrosion. And it actually costs four times less than a stainless steel butterfly valve.

In addition, the thermoplastic materials used in valves have a better resistance to abrasion than metallic valves. PVDF for example has a 5 to 10 times greater resistance than that of SS 304 and 100 times superior to PTFE lining. Finally, thermoplastic valves are also chosen because they are lightweight: easier transport, storage and installation, reducing logistics costs and accident risks.

And yes, thermoplastic valves are also economic:  for example a Hastelloy valve can be 10 times more expensive than a PVDF equivalent.

The best way to select a valve is always to consider the environment and usage. Of course we have excellent experience and can therefore give you very good advice about the appropriate valve for your application.
