Festo
535021
Pressure regulator MS12-LR
The Festo part number 535021 is an industrial component of the MS series in size 12, featuring a pilot-controlled diaphragm regulator structural design with constant output pressure, primary pressure compensation, secondary exhausting, and return flow characteristics. It operates within a pressure range of 0.08 MPa to 2.1 MPa and a regulation range of 0.15 bar to 16 bar, delivering a normal nominal flow rate from 12,000 l/min to 22,000 l/min alongside a secondary venting flow rate of 600 l/min using compressed air or inert gases. Built with a rotary knob actuator lock and an integrated pressure gauge, the unit supports in-line installation or mounting with a retaining bracket in any position under ambient temperatures from -10 °C to 60 °C.
