Electric actuator output torque valve operation should be 1.2-1.5 times the maximum torque. Electric butterfly valve operating thrust: the host structure electric valve actuators in two ways: one is not configured thrust plate. Output torque through the thrust plate stem nut is converted to output thrust. Direct output torque; the other is configured thrust plate. Output shaft rotation number: How many electric valve actuators and valve output shaft rotation number of the nominal diameter, stem pitch, thread the first few related. H is the height of the butterfly valve open for sale, according to M = HZS computing (M for electrical installations should meet the total number of turns .S for hydro valve stem transmission thread pitch, Z for the first few stem threads. Installation and maintenance 1, When installing smart butterfly valve to stop in the closed position. 2, open position the disc rotation angle should be determined. 3, butterfly with a bypass valve opening should be preceded Open. 4 bypass valve, accordance with the manufacturer's installation instructions for installation, the weight of a large butterfly, set a solid foundation for metallurgical butterfly |.
