3226/5857, 3226/5824, 3226/5825 type electric control valves and 3226/2780-1, 3226/2780-2 type pneumatic control valves are diverter or mixing valves used in heating, ventilation and air-conditioning systems. The valves are available for DN 15 to DN 50, G ½ to G 1 range. The control valve consists of a 3226 type three-way valve and an electric or pneumatic actuator.
The Samson 3226 series includes electric (3226/5857, 3226/5824, 3226/5825) and pneumatic (3226/2780-1, 3226/2780-2) three‑way control valves for heating, ventilation and air‑conditioning systems. The valves can be used as mixing or diverting devices and are available with welded, external‑thread or internal‑thread connections for DN15‑DN50 pipelines.
The manual provides working principles, installation guidelines, safety features, ordering information and detailed technical data such as pressure rating, temperature limits, dimensions and material specifications. It also lists the required power supplies for electric actuators and control signal ranges for pneumatic actuators. This manual is written in Chinese.
