. To prevent damage to O-rings and the valve seat, remove the one-piece ICM bonnet and function module from the valve body prior to welding the valve body in the line. For ICM 0 (3/4” size) the valve seat is not integrated with the valve bonnet and must be separately removed from the valve body with a 1 mm hex key prior to welding (see diagrams below). - Page 4 5. Install the bonnet/function module into the valve body. a. For ICM 0, make sure that the removable orifice seat is installed in the valve body with the small O-ring between the orifice seat and body. Make sure the bonnet gasket is installed and in good condition.
