2 Lines Valve Motorized Operation (20 Series)

20 Series Two-line Motorized Valve is applied to control on/off of the central air-conditioner terminal. To auto regulate the room temperature, it controls the cool/heat water flow and then through fan coil units to send air.

Characteristics:
1. Two ways normally off and three ways diffluence style. (DN15, DN20, DN25)
2. Valve body forged by brassiness, stainless steel stem and spring
3. Synthetic rubber valve disc, no bleb when turning off.
4. The Kv value of normally closed valve can be optioned locale and the default value is set to the Max when leave factory.
5. Backward spring inside.

Drivers:
1. The style using H/L voltage is supplied.
2. AC magnetic hysteresis synchronous motor makes operation quite
3. Manual drive pole.
4. Complanation design, less space used when actived.
5. Driver can be installed after the installation of the body of valve.
