Festo MS6-LR-1/2-D7-AS pressure regulator, part number 529993, is a core modular component of Festo MS6 series pneumatic service units. Designed with a precision diaphragm pressure regulation structure and secondary venting function, this regulator delivers highly stable air pressure output with minimal pressure hysteresis, effectively eliminating output pressure fluctuation caused by inlet pressure changes. It comes with a matched pressure gauge for intuitive real-time pressure monitoring, enabling convenient and accurate manual pressure adjustment via a detent rotary knob. The die-cast aluminium alloy housing features excellent mechanical strength and CRC2 corrosion resistance, paired with durable NBR diaphragm to ensure long-term stable sealing performance. Supporting a maximum flow rate of 5500 l/min, it adapts to high-flow industrial pneumatic systems. It can be installed in any position and perfectly combined with other MS6 series service unit modules to build integrated air source treatment systems. Widely applied in factory automation, mechanical processing and pneumatic equipment requiring precise and stable compressed air pressure control.
