721100205 Union FlowCtrl Ind Water PVC 150PSI Leak-Proof Valve

​1. Sanitary Flow Sensor for Precision Bioprocessing Applications​

The GF Signet 721100205 is an advanced sanitary flow sensor engineered for critical measurement applications in pharmaceutical and bioprocessing industries requiring EHEDG EL-Class I compliance. Featuring ​turbine-based measurement technology​ with ​ceramic bearings​ and ​316L stainless steel construction, this device delivers ​​±0.5% accuracy​ across ​0.5-60 L/min ranges​ with ​​≤80ms response time. Its ​IP69K-rated housing​ withstands ​150°C SIP cycles​ and ​100-bar CIP cleaning​ while meeting ​ASME BPE-2022 standards​ with ​Ra≤0.4µm surface finish. The sensor incorporates ​integrated temperature compensation​ and ​bidirectional flow detection​ capabilities, providing versatile installation options for WFI systems, buffer transfer lines, and CIP return monitoring applications. Designed for operation from ​​-20°C to +130°C, this sensor offers ​pulse output​ and ​4-20mA signals​ with ​programmable K-factors, ensuring ​long-term stability​ with ​**>36-month service life**​ in aggressive chemical environments.

​2. Technical Performance and Application Advantages​

This flow sensor excels in mission-critical bioprocessing applications including WFI distribution verification (0.5-5 L/min), CIP return flow monitoring, and high-precision buffer transfer control. The device incorporates ceramic bearing technology that ensures frictionless operation and 316L stainless steel wetted components that resist corrosive cleaners and sterilizing agents. Its ultra-smooth surface finish (Ra≤0.4 µm) prevents biofilm accumulation while the bidirectional flow capability enables flexible installation without directional constraints. The integrated temperature compensation system maintains accuracy across 0-100°C fluid temperatures, and quick-disconnect tri-clamp fittings facilitate rapid installation and optimal cleanability. The pulse output allows precise batch control while the 4-20mA output enables continuous process monitoring, making it ideal for pharmaceutical, biotechnology, and food processing applications requiring FDA 21 CFR 177.2600 compliance and EHEDG certification.

​3. Advanced Features and Regulatory Compliance​

The 721100205 utilizes a free-wheeling turbine with optical sensor detection, providing high-resolution flow measurement with 100 pulses per revolution for exceptional accuracy. The hygienic design meets EHEDG Class I criteria through crevice-free construction, self-draining orientation, and steam-sterilizable components supporting SIP cycles up to 150°C. Comprehensive regulatory compliance includes 3-A Symbol 74-03 for dairy applications, FDA 21 CFR 177.2600 materials registration, and EC1935/2004 for food contact applications. The programmable K-factor allows customization for various fluids, while sophisticated low-flow detection ensures reliable operation down to 0.5 L/min across all process conditions. ATEX Zone 2 certification enables safe deployment in hazardous areas with flammable solvents, while optional PROFIBUS PA output facilitates direct integration into automated process systems. Integrated HART communication provides comprehensive remote configuration, monitoring, and diagnostic capabilities for validation documentation and process management in regulated industries.
