FESTO LR-3/8-D-MIDI (159580) Pressure Regulator
The FESTO LR-3/8-D-MIDIis a precision pneumatic regulator from the reliable D-Series.It is designed to accurately control and maintain a constant output pressure regardless of fluctuations in the input air supply or variations in flow demand.
Constructed with a rugged die-cast zinc housing, this "Midi" size regulator is a staple in industrial automation.It features integrated primary pressure compensation and a secondary venting (relieving) function, allowing for the quick and safe reduction of downstream pressure when the setpoint is lowered. The rotary adjustment knob includes a built-in lock to prevent unauthorized or accidental pressure changes, ensuring system safety and process stability.
