Butterfly Valves


Type 2671 - Butterfly valve


2/2-way butterfly valve in metal for shutting off and controlling media flows. Based on the fact that the butterfly valve is available in various designs (intermediate flange, end flange) and in different materials, it meets the requirements of various applications and processes. Preferential areas of application for butterfly valves are, for example, the metal industry, power plant technology, paper industry as well as mining, shipbuilding and mechanical engineering. Further characteristics and advantages are: • Through shaft for self-centering disc --> even wear and low torque • PFA-coated shaft in the sealed area • Blow-out proof shaft seal • Spherically shaped disc • Notched handle in ductile iron: lockable in 10 adjustable positions

  • Manually operated / Automatable
  • High flow values
  • Shaft and body are non-wetted parts
  • Low torques
  • Zero leakage

Type 2674 - Plastic butterfly valve


2/2 way plastic butterfly valves used for control and on/off operations. Type 2674 can be connected via the mechanical interface (acc. to ISO 5211) with pneumatic (for example, type 2051 or 2052) and electrical rotary actuators (for example, type 3003, 3004 or 3005). Next to this, the valve is available with different kinds of liner (EPDM, FPM), housing (PVC-U, PP-GR) and disc (PVC-U, PP-H, PVDF, PVC-C) materials. Consequently, type 2674 is suited for various aggressive media and meets the requirements of different applications and processes.

  • Manually operated / automatable
  • For aggressive media
  • Low torques
  • Long lifespan
  • Maintenance friendly

Type 8805 - Butterfly valve with pneumatic rotary actuator


Type 8805 consists of a 90°swivel fitting (ball or butterfly valve) and a pneumatic rotary actuator. The rotary actuator is available as single or double-acting actuator. Type 8805 can be complemented by a positioner (8792), a pilot valve (6519) or several kinds of position feedbacks (1061).

  • Pneumatic rotary actuator
  • Accurate end position setting
  • Full bore flow
  • Favourable flow rates
