Series VH 780 — insertion paddle flow switches

• Brass or stainless steel version • DN 32 à DN 200 • Setting range: 0.2...90 m³/h • Flow velocity up to 4 m/s • Maximum pressure: 20 bar (stainless steel), 11 bar (brass) • High breaking capacity For use on clean liquids in pipework from DN 32 to DN 200 Heating systems Cooling circuits Lubrication circuits Heat pumps Compressors Industries: chemical, pharmaceutical and food The flow drives the paddle which, through the rotation of a cam, moves a carrier inside the body that operates a microswitch. The flow setting is chosen according to the pipe diameter, by selecting the right paddle (see table). The set point is adjusted with a screw (mounting in any position, upward flow).
