Festo
537148
Pressure regulator MS12-LR-G-D7-LD-AS
The Festo 537148 is a size 12 industrial component from the MS series, featuring a pilot-controlled diaphragm regulator designed with constant output pressure, primary pressure compensation, secondary exhausting, and a return flow characteristic. It operates within a pressure range of 0.8 bar to 21 bar and a regulation range of 0.5 bar to 12 bar, delivering a nominal flow rate between 13000 l/min and 22000 l/min using compressed air or inert gases. The unit includes a pressure gauge, a rotary knob actuator lock with detent that can be closed with accessories, and supports in-line installation or mounting with a retaining bracket in any position.

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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
