Valve actuator assembly599-03609 = rack and pinion linkage + OpenAir GCA161.1U electronic actuator, for modulating control; actuator prefix code 298 (298-XXXXX = linkage, actuator and valve assembly); linkage alone = 599-03610
Actuator typeElectro-mechanical, spring return, 'Electro-Mechanical - 24 VAC' in valve selection tables; brushless DC motor with stall protection
Actuator operating voltage24 VAC +/-20% or 24 VDC +/-10% (G-G0)
Actuator frequency50/60 Hz
Actuator power consumptionRunning 7 VA / 5 W; holding 5 VA / 3 W
Power consumption for transformer sizing (valve assembly)9 VA; max 9 actuators per Class 2 supply circuit (80% of transformer VA)
Actuator equipment ratingClass 2, in accordance with UL/CSA

Actuator fail actionSpring return; on power failure or when operating voltage is shut off all models return to the 0 position (bi-directional fail-safe spring return)
Direct / reverse acting (valve assembly)Direct-acting or reverse-acting control is set by the actuator's mounting orientation on the linkage (single end-stop tab upper left = direct, upper right = reverse); in both cases the actuator is engaged with the valve stem full up (min 1.80 in (46 mm) between bottom of linkage stem coupling and top of bonnet)
