Ball valve with internal thread for open and closed hot and cold water systems. The ball valve is actuated by a rotary actuator. Rotary actuators are controlled by commonly supplied control systems either modulating or 3-point, and drive the ball of the ball valve, which acts as the control element, to the position specified by the control signal. The valve opens anti-clockwise and closes clockwise. 

Features:

• Ball valves can be installed in any position from upright to horizontal. It is not permissible for the ball valve to be suspended, i.e. installed with the spindle pointing downwards.
• The requirements of VDI 2035 regarding water quality must be observed.
• Ball valves are control elements. To ensure they can perform the control function over the long term, the use of a dirt filter is recommended.
• The valve is airtight and maintenance-free.
