PVC Valves


What are the top 3 PVC valve applications? That's really an interesting question, considering the fact that Polyvinyl Chloride and other thermoplastic materials have been slowly but surely replacing more traditional ones, and not just in plumbing, other piping systems, and valves, but in just about everything, including building materials. Realistically, it might be presumptuous to list applications, such as Pool, HVAC, or Refrigeration systems as the top 3 when the list is virtually endless. We could just as easily say the use of PVC valves is favored by the medical world, chemical processing facilities, and countless manufacturers utilizing pneumatic-assisted assembly lines. It may be more prudent, then, to examine why PVC valves are such a great choice, and categorize their applications by their three top advantages, instead.

Top 3 Advantages of PVC Valves

  • Durability: A technical marvel, PVC is one of the most durable of man made materials. Extremely weather, chemical, and corrosion resistant, PVC valves are a natural match for any outdoor or underground piping system, or one that is exposed to chemicals or the threat of corrosion from either a media, or external influences. In an article by PVC Construct, an architectural company, it was estimated that at least 75% of PVC pipe can have 40 to 60 year life spans. While it's no trick to use metal valves on a PVC pipeline, it's preferable (and often mandated) that PVC valves be used, and would make sense, considering the material's longevity. This is one of the biggest reasons PVC valves are increasingly used for potable waterlines.
  • Non-toxic: In its final, solid form, PVC is perfectly safe for potable water, and is--in fact--the number one choice. It is not only non-toxic, it is completely, 100% Lead-Free, as well. In today's health conscious world, lead restrictions continue to grow less tolerant. While manufacturer's struggle to cast or mill metal valves with lower lead contents, manufacturer's of thermoplastics enjoy the advantage of never having to worry about it. Even PVC valve installation techniques bypass any use of lead.
  • Versatility: PVC is one of the easiest materials to work with, and PVC valves are no different. Typically, a PVC valve is fitted to the line, and sealed with a type of glue, for tight, fool-proof seals. And, being a kind of plastic, PVC can be molded into any shape, including virtually any metal valve configuration. There are even three piece PVC valves, known as True Unions, that allow the valve to be removed from any piping system without disturbing the end connections, making them ideal for any application that may require frequent inspections, repairs, or replacements.


Top 3 Applications?

It's hard to say, considering PVC's use in so many industries. It may be easier to just remember the advantages using PVC valves provides. Easy to manipulate and work with, cost-effective, and extremely resilient, thermoplastic valves can be used for just about any application where a PVC piping system exists or is called for. PVC valves will never rust, never rot, and never leach any harmful chemicals. Durable, versatile, and non-toxic, PVC valves are perfect for countless applications.
