Butterfly valve

pneumaticelectrichydraulic

Fully CNC machined for optimum resistance for heavy duty applications ! These dampers are primarily wafer design but can, if necessary, be produced with flanges, spool piece or lugg. The valve is intended to be used as an isolating (shutoff) or control (regulating) valve in which closing is realized by turning the disc attached to the shaft in a range of 0-90°. The valve is designed for bi-directional flow of the fluid where the tightness of the obturator depends on the design. Achievable class I – II – III according to Ansi FCI 70/2. The valves are equiped with adjustable stuffing box and graphite braids. Above 300°C, the valves are equiped with external bearing. It is possible to install a lantern ring in the stuffing boxes that will enable flushing and overpressure – securing a perfect tightness to atmospher in chemical applications. The face to face of these valves are kept to the shortest pattern but can be extended on request Actuator connection according to ISO 5211 adapted to work with customer actuators or on site actuators Applicable directives Declaration of C onformity in c ompliance with Machinery Directive CE Directive Declaration of C onformity in compliance with EU Directive PED Directive Tightness class possible class I, II and III ac c. to FCI 70-2 (ex ANSI B16.104)
