1. Lightweight and Economical Automation Solution
The GF 369 Wafer Check Valve in PVC-U/EPDM with PN6 rating and DN90 (d90) size offers a compact, corrosion-resistant solution for automated backflow prevention in industrial pipelines. Its wafer design allows installation between flanges, saving space in machinery while supporting vertical or horizontal mounting. The PVC-U body and EPDM seals resist aggressive chemicals and UV exposure, ensuring durability in water treatment, chemical processing, and wastewater systems. The non-spring design reduces mechanical complexity, minimizing maintenance needs in automated workflows. With a flow-optimized return cone structure, it balances low pressure loss with reliable shutoff, ideal for low-to-medium flow applications requiring bidirectional control.
2. Compliance and Performance for Hygienic Systems
Engineered for industrial automation, this valve meets NSF 61 and FDA standards, making it suitable for potable water and food-grade environments. Its bubble-tight sealing (ISO 5208 Class A) prevents contamination in sensitive processes, while the PN6 pressure rating ensures compatibility with standard pipelines. The lightweight construction (approx. 0.86–0.95 kg) simplifies robotic installation in automated assembly lines, and flame-retardant properties enhance safety in high-risk areas. Optional upgrades like stainless steel springs or Hastelloy components expand its utility in corrosive media, ensuring adaptability to diverse automation requirements.
3. Modular Design for Smart Integration
The GF 369’s modular structure supports seamless integration with actuators and sensors for IoT-enabled automation. Its reduced-bore design allows easy retrofitting with smart devices for real-time monitoring, while compatibility with ANSI and DIN flanges ensures global applicability. Ideal for wastewater treatment, irrigation, and chemical dosing systems, the valve’s low-friction operation reduces energy consumption in automated processes. GF’s 70-year expertise in plastic valves guarantees long-term performance, with a design lifespan exceeding 10 years in typical industrial conditions. This model combines cost efficiency with advanced automation readiness, delivering sustainable backflow protection for modern manufacturing and infrastructure.
