Proportional Pressure Control Valve
The Festo VPPL-3Q-3-0L40H-V1-A-S1-1 is a directly controlled piston regulator designed for precise pneumatic pressure management. It suits automation engineers and maintenance technicians who need closed-loop control in industrial systems. The valve operates with a 3-way proportional function and a soft sealing principle for reliable shut-off.
Integration Requirements and Benefits
This unit requires a DC supply between 21.6 V and 27.6 V with a residual ripple up to 10 % and draws a maximum of 26.7 W at 100 % duty cycle. It accepts a 0-10 V analog setpoint and provides a 4-20 mA feedback signal for process monitoring. The design frees up panel space by combining regulation, display, and diagnostics in a single housing with LED status indication.
Target Users and Limitations
The valve suits applications needing pressure regulation from 0.4 bar to 40 bar with a standard flow of 300 l/min and a maximum hysteresis of 0.2 bar. It is not for systems requiring short-circuit protection on the electrical connections or for environments exceeding moderate corrosion stress class 2. Buyers needing a safety position that maintains pressure during power loss should look elsewhere, as this model vents to 0 bar if the supply cable breaks.

Questions about this item
What pressure regulation range can the VPPL-3Q-3-0L40H-V1-A-S1-1 maintain during continuous operation?
The valve regulates outlet pressure from .4 bar up to 40 bar with a maximum hysteresis of .2 bar, and the standard nominal flow rate is 300 l/min.
How much electrical power does the valve draw at 100 % duty cycle and what heat considerations follow?
Maximum electrical power consumption is 26.7 W at a DC operating voltage of 21.6 V to 27.6 V with 10 % residual ripple; the unit is rated for 100 % duty cycle so sustained heat output matches this power level.
Which electrical connections and signal types must the existing control system provide for this valve to operate?
The valve requires a DC supply of 21.6 V to 27.6 V, accepts a 0 V to 10 V setpoint input, provides a 4 mA to 20 mA analog output, and includes reverse polarity protection on all electrical connections.
