DL1003 Electric 3-way Ball Valve – Full-Port Brass Actuated Valve for Diverting or Mixing Applications

The Coliter® DL1003 Electric 3-way Ball Valve is a high-performance actuated valve designed for reliable on/off flow switching in HVAC, water treatment, and industrial systems. Featuring a full-port brass ball with PTFE seals, it enables low-torque, bubble-tight shut-off and supports both L-port (diverting) and T-port (mixing/diverting) flow configurations depending on installation needs. Rated at PN16 (1.6 MPa) and suitable for media temperatures from 0°C to 110°C, the valve is driven by a robust electric actuator operating on 24V AC/DC or 220V AC. It includes standard features such as manual override and optional fail-safe (spring-return) functionality, ensuring operational safety during power loss. With its compact design, long service life, and compatibility with building automation systems (BAS), the DL1003 is ideal for applications including chiller bypass, boiler control, heat exchanger circuits, and smart fluid distribution networks.
