The ZPL220/ZPL220W series balanced cage control valve is a pressure-balanced regulating valve. Featuring a compact valve body design with high output force, its S-shaped flow passage incorporates a flow-guiding vane that optimizes balanced fluid distribution around the cage.
Product Overview
This design delivers: Minimal pressure loss. High flow capacity with wide adjustable range. Precise flow characteristics (compliant with IEC 60534-2-1-201/GB4213). Enhanced dynamic stability with low noise and reduced cavitation erosion and Leakage rate meeting ANSI FCI 70-2-2013 standards. When compressed air enters the actuator, the piston rod drives the plug to modulate valve opening. This movement proportionally adjusts gas flow for precise control. The ZPL220/ZPL220W series control valve is ideal for high/low temperature and high-pressure fluid control across industries including: Power Generation, Metallurgy, Chemical Processing, Petroleum, Textiles, Pharmaceuticals, Paper Manufacturing. The valve's material versatility and customizable designs ensure optimal performance in diverse automated process control systems.
