13. Flanged Valve Bait Torques <br />The valve end with the rubber flange shall be installed using the <br />backup rings provided. The sleeve split should be installed facing <br />downstream, with the split in the vertical position. <br />The installation bolt torque on the end flange bolts are Headed in the <br />table below. <br />RECOMMENDED MINIMUM BOLT TORQUE <br />Valve size Raft She Toreua fft'Ihl <br />1-1/2" <br />1/2"-13NC <br />20 <br />2" <br />5/8" - 11 NC <br />30 <br />2-1MY' <br />5/8"-11 NC <br />40 <br />3" <br />5/8" -11 NC <br />40 <br />4" <br />5/8" -11 NC <br />30 <br />5" <br />3/4" -1ONO <br />40 <br />6" <br />3/4" -10NC <br />30 <br />8" <br />3/4" -10NC <br />40 <br />10" <br />7/8" - 9NC <br />40 <br />12" <br />7/8"-9NC <br />50 <br />14" <br />1"-8NC <br />50 <br />18" <br />1"-8NC <br />50 <br />18" <br />1-1/8"-7110 <br />30 <br />20" <br />1-1/8"-7NC <br />30 <br />24" <br />1-1/4"-7NC <br />40 <br />30" <br />1-1/4"-7NC <br />30 <br />36" <br />1-1/2"-6NC <br />40 <br />42" <br />1-1/2"-6NC <br />50 <br />48" <br />1-1/2"-6NC <br />55 <br />54" <br />1-3/4"-5NC <br />60 <br />60" <br />1-3/4"-5NC <br />80 <br />92" <br />1-3/4"-514C <br />100 <br />Torque values are suggested minimum values. <br />Torque all flange bolts in a star pattern, first to 50%of tabulated <br />values, then homages to 100%of tabulated values.
