The ZCF-PU Series Pilot-Operated Diaphragm Anti-Corrosive Plastic Solenoid Valve is a 2-way, 2-position, pilot-operated solenoid valve engineered specifically for the precise control of aggressive industrial corrosive fluids. Comprising a comprehensive model range from ZCF-PU-10ES to ZCF-PU-50ES and covering nominal sizes from DN10 to DN50, this series features a robust valve body precision-molded from high-grade, non-metallic UPVC (Unplasticized Polyvinyl Chloride) or CPVC (Chlorinated Polyvinyl Chloride). These materials deliver exceptional chemical stability and corrosion resistance against various acids, alkalis, salts, and active chemical reagents.

The definitive technical advantage of this series lies in its pilot-operated diaphragm configuration, which requires a minimum differential operating pressure of 0.3 Bar. This specialized structural architecture effectively isolates the corrosive process fluid within the lower chamber, ensuring it remains completely separated from the internal metal components (such as the moving armature and springs) in the upper section. This breakthrough design completely eliminates the risk of fluid-induced metallic corrosion and prevents secondary metallic ion contamination of high-purity media. Operating within a nominal pressure rating of 0.3 to 8 Bar, it efficiently controls fluids with remarkably low electrical power consumption and high lifecycle reliability. It is widely applied in electroplating and pickling lines, chemical wastewater treatment, PCB manufacturing lines, semiconductor cleaning processes, pharmaceutical production, and automated systems handling corrosive gases or liquids.

Total Medium Isolation Architecture: Utilizing an advanced pilot diaphragm layout, the aggressive process fluid only comes into contact with the UPVC/CPVC body and the chemical-resistant elastomeric diaphragm. Internal moving metallic components, such as the plunger and springs, are perfectly isolated from the fluid, exponentially maximizing valve life in toxic chemical environments.

Outstanding Chemical Resistance: The valve body is available in both UPVC and CPVC engineering plastics. UPVC is ideal for standard acid/alkali processing, while CPVC yields enhanced resistance to high chlorination, chemical stress cracking, and cracking over time. Combined with premium anti-corrosive seals, it flawlessly endures high-concentration chemical media.

Efficient Pilot-Operated Low-Power Drive: By leveraging the internal fluid energy of the pipeline as the primary actuation force, the dynamic mechanical load on the solenoid coil is vastly minimized. Within the 0.3 to 8 Bar range, it yields sensitive, lightning-fast on/off response alongside low thermal emission, making it ideal for continuous duty cycles.

Versatile International Threaded Ports: Available with G thread and NPT thread connection variants, spanning nominal diameters from DN10 to DN50. This guarantees full compatibility with both domestic and international chemical piping infrastructure standards.

Upgraded Industrial Protection: Equipped as standard with an IP65-rated industrial-grade coil featuring a robust DIN connector. It provides excellent waterproof, dustproof, and ambient acid-mist corrosion resistance, guaranteeing continuous and safe performance even in high-humidity electroplating or chemical plant environments.
