Product: DC 12–24V G3/4 (DN20) 2-way motorized brass ball valve Key benefits Reliable, long-lasting construction: Forged brass body provides mechanical strength and consistent performance over time for HVAC water systems. Precise, motorized control: 2-way ball valve operated by a DC 12–24V actuator gives accurate opening/closing of hot and cold water lines for stable system operation. Space-saving installation: Compact design allows mounting close to walls or inside tight cabinets, freeing up installation room in crowded plantrooms or service closets. Quiet operation: Low-noise actuator delivers efficient control without disturbing occupants, ideal where noise must be minimized. What it does and why you need it Controls fluid direction and flow rate in HVAC terminal applications, helping maintain setpoints and system balance. Replaces manual valves or noisy actuators to improve automation, responsiveness, and occupant comfort. Durable brass construction reduces the need for frequent replacement, lowering maintenance and downtime.
