About Plastic Valves
What Is Plastic and Why Is It Used in Valves?
Plastic valves are made from durable polymers such as PVC (polyvinyl chloride), CPVC, PP (polypropylene), and PVDF, depending on the application. These materials offer excellent corrosion resistance, lightweight construction, and chemical compatibility, making plastic an ideal choice for non-metallic valve systems where exposure to aggressive media or weight limitations are concerns.
Why Plastic for Valves?
- Excellent Corrosion Resistance: Ideal for chemicals, acids, and saltwater where metal valves may degrade.
- Lightweight & Easy to Handle: Reduces shipping and installation costs.
- Non-Conductive: Safe for applications where electrical conductivity is a risk.
- Cost-Effective: Typically more affordable than metal alternatives, especially in low-pressure systems.
- Low Maintenance: Resistant to scaling, rust, and general wear in non-abrasive environments.
Common Applications of Plastic Valves
- Chemical Processing: For handling corrosive acids, alkalis, and solvents.
- Water Treatment & Filtration Systems: In clean water and waste applications.
- Agriculture & Irrigation: Lightweight and corrosion-resistant for fertiliser and water systems.
- Swimming Pools & Spas: Non-corrosive, chlorine-resistant flow control.
- Food & Beverage Industry: In specific cases using food-safe grades of plastic.
