Screw on the nuts firmly but not excessively. The inside nuts have no weight-bearing function. Theyonly serve to secure the valve when the feeder installed below is stripped )Apply a thin layer of liquid seal before fitting the valve to the connecting )Close the valve only when material is )Clean the valve regularly with either air or water. This is particularly important if the material handled tends to compact or to solidify due tolonger shutdown )Operating temperature < 80 )The material weight resting on the disc must never be greater than its maximum static torque. As it is difficult to calculate this weight exactlydue to varying material properties, as rule of thumb, one may consider there are no problems with bulk densities < t/m3 in standard hoppersand silos8)Refer to assembly instructions on WAM actuators included in each AND MAINTENANCEASSEMBLY INSTRUCTIONS WHEN USING WAM BUTTERFLY VALVEREPLACEMENT OF SEALS IN DRIVE HEAD AND IN END BEARING ASSEMBLYR eferring to carry out the following steps:1) Close silo ) Empty screw ) Disconnect electric motor from ) Open inspection ) Prevent the inlet screw (D) from sliding out by introducing a plank (A) into the inlet hatch ensuring plank firmly locks ) Ensure eyebolt (F) of electric motor is tightly screwed ) Fix the lifting device to the eyebolt (F).
