Our 20mm plastic stem dosing valve offers exceptional performance for water treatment and fluid management applications where corrosion resistance and reliable operation are essential. This precision valve features a durable polymer construction that withstands demanding water treatment chemicals while providing accurate flow regulation for chemical dosing. The metering mechanism allows for fine adjustment of fluid passage, enabling operators to achieve optimal chemical feed rates for various water treatment processes. Unlike metal valves, this plastic stem version eliminates rust concerns and reduces system contamination, making it ideal for potable water treatment, wastewater processing, and industrial water management applications. The valve design incorporates a smooth operation mechanism with clear positional indicators for easy adjustment and flow verification. Available with multiple connection options including threaded and flanged fittings, this versatile valve adapts to various installation requirements in water treatment facilities. The precision-engineered components ensure consistent performance and long service life even with frequent adjustments in harsh water treatment environments. With its excellent resistance to water treatment chemicals and corrosion, this 20mm dosing valve provides reliable operation in handling chlorine solutions, flocculants, pH adjusters, and other water treatment chemicals across municipal and industrial applications.
