Product Description

Details

Features

  • Mode of operation The butterfly valve is opened or closed completely by an open-close rotary actuator. Continuousrotary actuators are controlled by a commercially available controller and move the valve discsinto any position desired. The disc made of stainless steel is pressed into the soft-sealing EPDM seat by a rotarymovement and ensures leakage rate A (tight). The flow rate losses are slight in open position and the kvs value is high.

  • Manual override Manual throttling or shut-off 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° ; 9 = 90° ). – With worm gear (DN 25 ... 700): Steplessly adjustable (self-locking) with position indication.
