Note：
DN50(2”)~600(24”)Type “LT” butterfly valves are suitable for the pressure of pn10MPa and PN1.6MPa grade separately two dimensions in one column show the connedion dimensions of PN1.0/PN1.6MPa pressure grade.For the connection dimensions of pipe flanges mounted to the valves, please refa to the conn-ection Dimensions of flanges Table.The upper flanges of the valves are suitable all types of fitted with electric,wormgear,manual,prieumatic and actuators.
Difference between Type ”A” and “LT”: Both Type “A” and “LT” have the same construction and performances and are materials. The main difference between then is that type “A” valves are mounted betweenpipe flanges,(wafer type)by bolts (or extended hexagon-head),while type “LT” can be either mounted between two pipes by ordinary hexagon head boits or mounted on the pipe end (lugged-type), As the valve is used at the end of pipe line it is necessary to indicate in order.
●Above two kinds of versions are given clear in dication of by user in the order on trad. ●The flange links the size and fits the standards such as G4216,DIN2501，BS4504，BS10-E,JISB2220，AS2129，ANSI B 16.1 etc, and must give clear indication of in the contract user. |
