Flowrite 599 Series SKB/C/D 62UA Electronic Valve Actuator Advanced Features
With normally-closed valves, "direct-acting" means that with a 0 Vdc signal input, the valve
is closed.
With Normally-open valves, "direct-acting" means that with a 0 Vdc signal input, the valve
is open.
Input: 0 to 10 Vdc
4 to 20 mA
0 to 1000 ohm
The valve body assembly determines the complete assembly action.
Table 3.
Setting the Stroke Limit Control
The rotary switches LO and UP can be
used to apply an upper and lower limit
to the stroke in increments of 3% up to
a maximum of 45%.
