Industrial Plastic Valves

Industrial plastic valves are crucial components in various industries for controlling the flow of liquids and gases. Unlike their metal counterparts, they offer superior resistance to corrosion and chemicals, making them ideal for handling aggressive or sensitive media. They are also lightweight, which simplifies installation and maintenance.

1. Common Materials Used in Plastic Valves

Material Max. Temperature Chemical Resistance Typical Applications
PVC-U 60 °C Acids, alkalis, salts; not resistant to aromatics, ketones Water supply & drainage, electroplating, wastewater
CPVC 95 °C Same as PVC-U, with higher temperature resistance Hot water, chlor-alkali, chemical pipelines
PP-H/PP-R 90 °C Resistant to most acids/alkalis/salts; not resistant to oxidizing acids Food, pharmaceuticals, deionized water
PVDF 140 °C Strong acids, halogens, solvents, ultrapure water Semiconductors, lithium batteries, ultrapure systems
PTFE 200 °C Almost universal, low friction Strongly corrosive media, high purity, diaphragms/valve seats
PFA 260 °C Comparable to PTFE, can be injection molded High-purity valve linings, fittings

2. Types of Industrial Plastic Valves

Valve Type Principle Advantages Typical Applications
Ball Valve 90° rotary on/off Quick opening, low pressure drop, full bore On/off control, pure water, chemicals
Butterfly Valve Disc rotation throttling Lightweight, space-saving, large diameter Wastewater, cooling water, coarse flow control
Diaphragm Valve Elastic diaphragm up/down Zero leakage, no packing High purity, particle-containing, aseptic systems
Check Valve One-way flow prevention Backflow prevention, maintenance-free Pump outlet, siphon protection
Needle Valve Tapered plug fine adjustment Precise flow/pressure regulation Dosing, sampling, laboratory
Solenoid Valve Electromagnetic coil drive Remote/automatic switching Dosing systems, automated production lines

3. Connection Methods Overview

  • Solvent Cementing (PVC/CPVC): Low cost, DN15–200 mm.
  • Heat Fusion Welding / Socket Fusion (PP, PVDF): Leak-free, DN20–315 mm.
  • Threaded (NPT/BSP): Small diameter, easy maintenance, DN8–50 mm.
  • Flanged (ANSI 150#/PN10): High pressure or large diameter, DN50–400 mm.

4. Applications of Industrial Plastic Valves

Industrial plastic valves are used in a variety of industries and applications, including:

  • Water and Wastewater Treatment: Due to their corrosion resistance, plastic valves are ideal for handling the various chemicals used in water and wastewater treatment processes.
  • Chemical Processing: The chemical resistance of plastic valves makes them essential for safely handling aggressive and corrosive chemicals.
  • Food and Beverage: Plastic valves are often used in the food and beverage industry because they are easy to clean and do not contaminate the product.
  • Pharmaceuticals: High-purity plastic valves, such as those made from PVDF, are used in pharmaceutical manufacturing to prevent contamination.
  • Aquatics and Aquariums: PVC valves are commonly used in swimming pools, aquariums, and other aquatic applications due to their durability and resistance to an array of water treatment chemicals.
  • Industrial Plating and Metal Finishing: The ability to handle corrosive acids and other chemicals makes plastic valves a good choice for these industries.

5. Three-step method for selection

  1. Medium & Concentration:
    • Check the chemical compatibility table → Prioritize PVDF/PTFE for strong corrosion.
  2. Temperature & Pressure：
    • ≤ 60 ° C / ≤ 1 MPa → PVC-U;
    • ≤95 °C / ≤1.6 MPa → CPVC；
    • 95°C or strong solvent → PVDF/PTFE.
  3. Functional requirements
    • Quick open/close → Ball valve;
    • Sterile/granular → Diaphragm valve;
    • Remote control → Solenoid valve/Pneumatic actuator.​
