As an option to the ASA suction units and butterfly flanges we offer mechanical and inductive limit switches.
The limit switch can be mounted on the standard block for monitoring matters.
The lever position corresponds to the valve position. Thus the aperture angle is well-defined even in mounted state. The handle direction (clockwise or counter clockwise) can be changed by turning the switch bracket. Please note that the butterfly flange may only be opened in mounted state and with greased or lubricated sealing.
