The valve features a robust ductile iron body with epoxy coating and stainless steel trim to ensure durability, corrosion resistance, and consistent sealing performance. Its factory-mounted GMX24-MFT actuator operates on AC/DC 24 V and supports MFT programmable control, allowing flexible configuration for modulating, on/off, or floating point operation. Engineered for maintenance-free service, the assembly provides stable performance and precise positioning across the full operating range. Key Features High-Performance Butterfly Valve Assembly: DN 3-inch valve with a Cv of 302 supports efficient flow control with low pressure drop in hydronic systems. Modified Equal Percentage Flow Characteristic: Optimized flow curve ensures smooth modulation and accurate control across varying load conditions. Integrated MFT Programmable Actuator: GMX24-MFT actuator supports 2…10 V, 4…20 mA, on/off, and floating point control from a single configurable device. Non Spring Return Operation: Maintains the last commanded valve position during power loss for stable and predictable system behavior. Durable Valve Construction: Ductile cast iron body with epoxy coating and stainless steel disc and stem provide long-term reliability. Tight Shutoff Performance: Rated for 200 psi close-off pressure with zero leakage to ensure effective isolation when closed. Service-Friendly Design: External manual override push button and mechanical position indication simplify commissioning and maintenance. The F680HD+GMX24-MFT-X1 delivers the reliability and precision required for accurate butterfly valve flow control in commercial HVAC hydronic applications.
