Festo
The Festo Size 2 industrial component from the MS series features a directly controlled diaphragm regulator delivering a constant output pressure with secondary exhausting and a return flow characteristic. It operates within a pressure range of 1 bar to 10 bar (0.1 MPa to 1 MPa) across a regulation range of 0.5 bar to 7 bar, providing a normal nominal flow rate of 170 l/min using compressed air or inert gases. Equipped with a rotary knob with detent for actuator locking and an integrated pressure gauge displaying in MPa, this unit is rated for ambient, medium, and storage temperatures from -5 °C to 50 °C.
