[2] Valve maximum operating pressure differential (MOPD) to be reduced by 25% from standard ratings.
[3] ISO connections are not recognized by CSA or UL standards
[4] SMA11, CMA11, SMM11, CMM11, SMA21, CMA21, SMM21 Series electro-mechanical valves meet the essential requirements of the Low
Voltage (73/23/EEC), EMC (2004/108/EC) and Gas Appliance - GAD (90/396/EEC) Directives. The Gas Appliance Directive only covers the
use of commercially available fuels (natural gas, butane, town gas and LPG). MD stands for Machinery Directive (98/37/EC).
[5] Special service fuels: Valve maximum operating pressure differential (MOPD) to be reduced from standard ratings
[6] All electro-mechanical valves except HMA11 Series are approved for use with No. 1 and No. 2 fuel oils. Swinging gate style valves are pref-
erable for liquid service.
