Principle of operation: 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 override: Manual throttling or shut-off can be carried out with a lever or a worm gear (see «Accessories»). -With lever (DN25…150): Adjustable in 10 ratchet steps with position indication ( 0 = 0° (angle); 9 = 90° (angle) ) -With worm gear (DN25...700): steplessly adjustable (self-locking) with position indication.
