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
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.
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).
