(a) Those utilizing 1/2 hp or larger motors; or (b) Those intended for use on valves connected in larger than 3- inch pipe size systems.
1.4 This Standard contains requirements for electrical features of valves and requirements for mechanical features of valves that affect their safe operation.
1.5 This Standard does not include requirements for mechanical and operational features that do not directly affect the safe operation of a valve.
