PVC Knife Gate Valve
PVC Knife Gate Valve – Lightweight, Corrosion-Resistant Flow Control Solution
A PVC knife gate valve is designed for reliable shut-off and flow control in low-pressure pipelines carrying liquids, slurries, and light solids. Unlike traditional metal valves, PVC construction provides excellent corrosion resistance, lightweight handling, and cost-effective performance, making it ideal for industries where chemical resistance and easy installation are priorities.
⚙️ Key Features & Advantages
Corrosion Resistance – Perfect for chemical processing, wastewater, and marine applications.
Lightweight Design – Easy to transport, install, and maintain compared to metal valves.
Smooth Operation – Knife-style gate cuts through liquids and soft solids with minimal effort.
Cost-Effective – Lower initial cost and reduced maintenance needs.
Versatile Connections – Available in wafer, flange, or lug style for flexible installation.
Sizes Available – From DN50 (2″) up to DN400 (16″) to meet different flow requirements.
🏭 Applications
PVC knife gate valves are widely used in:
Wastewater Treatment Plants – Handling sludge and non-abrasive liquids.
Chemical & Fertilizer Plants – Resistance to corrosive chemicals and acids.
Food & Beverage Industry – Safe for certain liquid handling processes.
Aquaculture & Irrigation – Lightweight solution for water control.
Swimming Pools & Water Parks – Non-corrosive, reliable water shut-off.
