Product Overview
The FESTO VPPM-6L-L-1-G18-0L6H-A4P-S1 is a precision pneumatic proportional pressure regulator from Festo’s VPPM series, engineered for continuous, stepless pressure regulation in electro-pneumatic control loops. Unlike conventional on/off solenoid valves, this device modulates its internal valve spool proportionally to an analog electrical setpoint signal (0–10 V or 4–20 mA), delivering infinitely variable output pressure that tracks the command signal with high repeatability. With a nominal size of 6 mm and G1/8 threaded ports, the unit is optimized for compact flow ranges while maintaining excellent regulation dynamics. The integrated closed-loop control electronics compare the actual downstream pressure—sensed by an internal pressure sensor—against the setpoint, continuously correcting the valve position to compensate for supply pressure fluctuations and flow disturbances. This makes the VPPM-6L an ideal choice for force-controlled clamping, tensioning, web guiding, and any pneumatic process requiring precise, programmable pressure rather than fixed mechanical regulation.
