Industrial Automation Valve: GF PVC-U/EPDM/375 Union Ball Valve
The GF PVC-U/EPDM/375 Union Ball Valve is a robust industrial automation solution designed for non-critical fluid control applications. Constructed with a durable PVC-U body, this valve offers excellent corrosion resistance against acids, alkalis, and saltwater, making it ideal for chemical processing, water treatment, and agricultural irrigation systems. It features a DN63-DN75 nominal diameter range (d63-d75) with PN16 pressure rating for smaller sizes and PN10 for larger diameters, ensuring reliable performance under moderate pressures. The union design allows for quick installation and maintenance without disturbing the pipeline, while multiple connection options—including socket welding, threading, and flange—enable compatibility with ISO, BS, ASTM, and JIS standards.
High-Performance Sealing and Operational Efficiency
Equipped with an EPDM O-ring and PTFE ball seal, the GF 375 Union Ball Valve provides superior leak-tightness and smooth operation across a wide temperature range of 0°C to 90°C. The dual-seal system ensures long-lasting durability even in challenging environments, reducing downtime and replacement costs. The lightweight yet rigid PVC-U structure minimizes system load, while the ergonomic handle offers precise on/off control with minimal effort. This valve is suitable for handling corrosive media, pure water, and chemical slurries, making it a versatile choice for industries such as pharmaceuticals, food processing, and wastewater management.
Reliable Design for Diverse Applications
Engineered to meet international quality standards, the GF 375 Union Ball Valve combines simplicity with advanced functionality. Its compact design saves space in tight installations, and the hygienic construction complies with FDA and NSF regulations for food and beverage applications. Optional accessories like limit switches, solenoids, and positioners enable integration with automated control systems, enhancing operational flexibility. Whether used in irrigation networks, chemical dosing systems, or general industrial pipelines, this valve delivers consistent performance, low maintenance, and compliance with global safety requirements, establishing it as a trusted choice for professionals worldwide.
