For many years, most valves used for industrial applications were made from metals like brass or bronze. Some are also made from stainless steel. However, thanks to modern plastics like polyvinyl chloride (PVC), valves are made from less expensive and extremely durable plastics. You can see PVC check valve applications in many settings today and here are some of their benefits and uses.
What are Check Valves?
Commonly called one-way valves, check valves are designed to keep the flow in one direction only. This is essential in applications where backflow could cause damage to materials or equipment. One of the most simple and effective valves is the one-way ball valve. A ball mechanism with pressure from a spring forms a seal against the inlet port. However, once fluid flows into the port, it pushes the ball back against the spring. This checking system keeps fluid flowing only in one direction, and when flow stops, the valve prevents backflow into the system, automatically.
What is PVC?
Polyvinyl chloride is a thermoplastic that’s either rigid or flexible. Rigid PVC is used for valve bodies, pipe, and many other applications. It is a form of plastic and using it for applications like the PVC check valve offers a lot of benefits.
Benefits
Plastic valves can be used to replace a wide range of metal valves. Modern plastics see use in applications like hot water and situations that would melt plastics of the past.
PVC check valve applications give you the same anticorrosion protection that you get from brass, bronze, or stainless steel. However, this protection comes at a fraction of the cost of many metal valves. PVC valves are lighter and servicing them is usually a simple matter. A trusted valve manufacturer can give you both stock and custom PVC valves for your business.
