The Uses and Properties of Plastic Lined Valves
High-Quality Lined Pipe Accessories for Demanding Applications
Plastic lined valves combine the strength of metal housings with the corrosion-resistant properties of engineered plastics such as PTFE, PFA, or other fluoropolymers. The result is a versatile flow control solution designed to withstand aggressive chemicals, high temperatures, and abrasive slurries.
Industries that commonly rely on plastic lined valves include:
- Chemical processing
- Pharmaceuticals
- Water treatment
- Pulp and paper
- Mining and minerals
- Food and beverage production
Key benefits of plastic lined valves include:
- Excellent resistance to corrosion and chemical attack
- Long service life with minimal maintenance
- Smooth internal surfaces for reduced pressure drop
- Compatibility with a wide range of piping systems
Types of Plastic-Lined Valves We Offer
Diaphragm Valves
Plastic lined diaphragm valves are popular in industries requiring precise throttling and shut-off control. A flexible diaphragm acts as a barrier between the process fluid and valve components, eliminating contamination risks. These valves are particularly well-suited for applications involving slurries, viscous fluids, and corrosive chemicals. Their simple design also makes them easy to maintain and highly reliable.
Ball Valves
Lined ball valves combine a robust metal body with a fully encapsulated ball interior. This design ensures smooth operation and excellent sealing even in harsh conditions. Plastic lined ball valves are widely used where tight shut-off is needed, such as in chemical transfer lines, industrial gas systems, and wastewater treatment. They allow for quick on/off operation while maintaining resistance to corrosion and wear.
Plug Valves
Plastic lined plug valves feature a cylindrical or conical plug that rotates to control flow. With their lined interior surfaces, these valves provide excellent protection against corrosive media. They are often used in chemical and petrochemical plants where reliable isolation and low torque operation are essential. The compact design also makes them ideal for systems where space is limited.
Butterfly Valves
Lightweight yet strong, plastic lined butterfly valves are designed for large-diameter flow control. Their lined disc and body provide full protection against aggressive chemicals, making them suitable for handling acids, caustics, and abrasive slurries. These valves are valued for their quick quarter-turn operation, low pressure drop, and cost-effective installation in both new and retrofit systems.
Check Valves
Plastic lined check valves allow fluid to flow in only one direction, protecting pumps, compressors, and piping from backflow. The corrosion-resistant lining ensures that the valve operates smoothly even in demanding environments. Industries dealing with aggressive chemicals, brine solutions, or high-purity water commonly rely on lined check valves for dependable system protection.
Process Sampling Valves
For industries that require safe and representative sampling of process fluids, plastic lined sampling valves offer a reliable solution. Their corrosion-resistant linings ensure that samples are not contaminated by metal surfaces, while also protecting operators from exposure to hazardous chemicals. These valves are an important component in quality control, compliance testing, and process optimization.
