64985 Union Flow Reg Ball Valve Ind Water Treatment PVC 150PSI Leak-Proof

1. Sanitary Flow Sensor for Bioprocessing Applications​

The GF Signet 64985 is a high-purity flow sensor engineered for precision measurement in pharmaceutical and bioprocessing applications requiring EHEDG compliance. Featuring a ​turbine-based measurement principle​ with ​ceramic bearings​ and ​316L stainless steel construction, this device delivers ​​±1% accuracy​ across ​0.5-20 L/min ranges​ with ​​≤100ms response time. Its ​IP69K-rated housing​ withstands ​150°C SIP cycles​ and ​chemical exposure​ while meeting ​ASME BPE standards​ with ​Ra≤0.4µm surface finish. The sensor incorporates ​integrated temperature compensation​ and ​bidirectional flow detection​ for versatile installation. Designed for WFI systems, buffer transfer, and CIP return monitoring, this sensor provides ​pulse output​ and ​4-20mA signals​ with ​programmable K-factors. Certified for ​​-20°C to +130°C operation, it enables ​long-term stability​ with ​**>24-month service life**​ in most sanitary applications.

​2. Technical Performance and Application Advantages​

This flow sensor excels in mission-critical processes including WFI distribution verification (0.5-5 L/min), CIP return flow monitoring, and buffer solution transfer control. Key advantages include ceramic bearing technology ensuring frictionless operation, 316L stainless steel wetted parts resistant to corrosive cleaners, and ultra-smooth surface finish (Ra≤0.4 µm) preventing biofilm accumulation. The sensor's bidirectional flow capability allows flexible installation without flow direction constraints, while temperature compensation ensures accuracy across 0-100°C fluid temperatures. With quick-disconnect tri-clamp fittings and crevice-free design, it reduces installation time and ensures optimal cleanability. The device's pulse output enables precise batch control, while 4-20mA output provides continuous flow monitoring for process automation in hygienic applications requiring FDA 21 CFR 177.2600 compliance.

​3. Advanced Features and Compliance Certification​

The 64985 utilizes a free-wheeling turbine with optical sensor detection providing 100 pulses per revolution for high-resolution flow measurement. Hygienic design features include crevice-free construction meeting EHEDG Class I criteria, self-draining orientation, and steam-sterilizable components supporting SIP cycles up to 150°C. Compliance coverage includes 3-A Symbol 74-03, FDA 21 CFR 177.2600 materials registration, and EC1935/2004 for food contact materials. The sensor's programmable K-factor allows customization for different fluids, while low-flow detection down to 0.5 L/min ensures reliable operation in all process conditions. ATEX Zone 2 certification enables deployment in hazardous areas with flammable solvents, and optional PROFIBUS PA output facilitates direct integration into process automation systems.
