DC 0...10 V control signal (for SSA161E.05HF)
Combi valves VPI46../VPP46.. in combination with SSA161E.05HF have equal-percentage
characteristics.
● The valve opens / closes in equal percentage ratio
to the control signal at Y.
● At DC 0 V, actuator stem extended, the valve is
fully closed.
● When no power is supplied, the actuator maintains
its current position.
● This actuator provides a DC 0…10V position
feedback signal proportional to the stroke of the
actuator stem.
Y = Control signal Y [V]
H = Percentage of calibrated valve stroke

Delivery
Valves and actuators are supplied in separate packages. For easier valve assembly, the
position of the actuator stem (spindle) is fully retracted.
