• Kvs adjustable 0.5...8 m3/h
• Factory setting 5.7 m3/h
• Body hot pressed brass
• Closing element chrome-plated brass
• Stem brass
• Stem seal O-ring EPDM

Mode of operation: The ball valve is operated by a rotary actuator. The rotary actuator is controlled by an open-close signal or by a standard modulating or 3-point control system and moves the ball of the valve – the throttling device – to the position dictated by the control signal. Open the ball valve counterclockwise and close it clockwise.

Simple direct mounting: Tool-free snap assembly. The actuator can be plugged on the valve by hand (Caution! Just vertical movements). Pins must match the holes on the flange. The mounting orientation in relation to the valve can be selected in 180° increments. (Possible two times)
