Festo
564143
Pressure regulator MS9-LR-NG-D7-AG-PSI-AS
The Festo 564143 is an industrial component utilizing a pilot-actuated diaphragm regulator design from the MS series in size 9, featuring a constant output pressure controller function with initial pressure compensation, secondary exhaust, and return flow. Weighing 1,400 g with a robust aluminum die-cast subbase and PA-reinforced cover, this RoHS-conforming unit operates within a working pressure range of 0.8 to 20 bar and a pressure control range of 0.3 to 12 bar across medium and ambient temperatures of -10 to 60 °C. The assembly supports any position with optional mounting types including line installation, front panel installation, or with accessories, and incorporates a pressure gauge alongside a lockable actuator lock with accessories.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
