Festo
153509
Differential pressure regulator LRLL-1/2-QS-12
Engineered with a constant differential pressure controller function and a return flow characteristic, the Festo 153509 industrial component features a directly controlled piston regulator housed in reinforced PBT with a nickel-plated brass screwed plug. This screw-in unit accommodates R1/2 and QS-12 pneumatic connections, delivering a nominal flow rate of 730 l/min open and 700 l/min closed across a 2 bar to 6 bar pressure regulation range. Operating with compressed air conforming to ISO 8573-1:2010 [7:-:-] at an inlet pressure up to 9 bar, the 105 g assembly includes a counter-locking actuator and supports any mounting 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.
