The 3-way valve design supports both mixing and diverting applications, enabling stable control of supply and return water circuits. Its modified equal percentage characteristic improves controllability across a wide operating range, even under partial load conditions. The factory-fitted non-fail-safe actuator provides proportional modulation using a standard 2–10 V control signal and is suitable for applications where spring return safety action is not required. Key Features Three-way globe valve design: Supports both mixing and diverting flow control strategies in hydronic HVAC systems. Precise modulating control: Accepts a 2–10 VDC control signal for smooth, proportional valve positioning. High control accuracy: Modified equal percentage characteristic with linear B–AB port behavior improves regulation stability. Low leakage performance: ANSI Class VI leakage rating ensures tight shutoff and efficient system operation. Robust valve construction: Bronze body with brass and bronze trim supports long service life in water and glycol systems. High pressure capability: ANSI Class 250 rating with up to 400 psi below 150°F for demanding installations. Integrated actuator assembly: Supplied factory-mounted to ensure correct alignment, stroke matching, and reliable operation. The G340B-N+SVB24-SR delivers the reliability and precision required for accurate three-way flow control in commercial HVAC and building automation systems.
