Festo
The Festo 543553 is an industrial size 4 MS-series on/off valve filter regulator featuring a 40 µm filtration grade, a manual rotating condensate drain with a 19 ml maximum condensate volume, and a plastic bowl guard. It operates within a pressure range of 0.15 MPa to 1.4 MPa (1.5 bar to 14 bar / 21.75 psi to 203 psi) and provides a pressure regulation range of 0.1 MPa to 1.2 MPa (1 bar to 12 bar / 14.5 psi to 174 psi) with a normal nominal flow rate of 1000 l/min. Designed for vertical ±5° mounting with a rotary knob actuator lock that can be closed with accessories, this component includes a pressure gauge and utilizes compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases as operating media.
