Design
Butterfly valve of flangeless type. It has rubber-lined de-tachable valve liner, which also serves as sealing for pipeflanges.The disc and shaft are made of stainless steel.The valve is equipped with an actuator, alternatively- hand lever DN 80...200- manual gear DN 80...600- electric, pneumatic or hydraulic actuator
Face to face lengths according to SFS 4132 series 20 andISO 5752 series 20
Connection in accordance with SFS 2123 = DIN 2501PN 16, PN 10 between drilled flanges
Butterfly valves are supplied with following actuator options:
- a lever or gear,- electric , pneumatic or hydraulic actuators.
Hand leverA lever is suitable for manual operation of small sizes ofbutterfly valves DN 80 to 200. The position of the disc canbe firmly fixed in any position between open and closedby the locking device incorporated. The hand lever is sup-plied positioned crosswise to the pipe with the valve closed.
