Coliter®’s three-way ball valves enable precise flow direction control, mixing, or isolation in HVAC, process, and industrial fluid systems. The series includes the Q44F L-port (90°) three-way ball valve for switching flow between two outlets, and the Q45F T-port (straight-through) type for mixing or diverting flows from a common line. Available in manual (Q44F/Q45F), gear-operated (Q344F/Q345F), pneumatic (Q644F/Q645F), and electric (Q944F/Q945F) actuation, these valves feature forged brass, carbon steel, or stainless steel (304/316) bodies with PTFE or reinforced soft seats for bubble-tight shut-off (ISO 5208 Class VI). Rated at PN16 (1.6 MPa) and suitable for temperatures up to 180°C, they offer low torque, full-port flow, and reliable operation—ideal for chiller bypass, heat exchanger control, and dual-circuit distribution.
