Butterfly valve with Wafer types

• For open and closed cold and warm water systems
• For switching heat generators or cooling machines on/off

Features

• The butterfly valve is opened or closed completely by an open/close rotary actuator. Continuous rotary actuators are connected by a commercially available controller and move the valve to any position desired. The valve disk made of stainless steel is pressed into the soft-sealing EPDM seat by a rotary movement and ensures leakage rate A (tight). The pressure losses are slight in the open position and the kv value is at a maximum.
• Manual throttling or isolation can be carried out with a lever or a worm gear (see «Accessories»).
  • • With lever (DN 25…150): Adjustable in 10 ratchet steps with position indication ( 0 = 0° (angle); 9 = 90° (angle) )
    • With worm gear (DN 25...700): steplessly adjustable (self-locking) with position indication.
