Festo
197538
Pressure regulator LRB-D-7-O-MIDI
The Festo 197538 is a Midi size industrial component from the D series, featuring a directly controlled diaphragm regulator with continuous compressed air supply and a rotary knob actuator lock with detent. Operating within a pressure range of 0.5 bar to 7 bar and a maximum operating pressure of 16 bar, this unit delivers a normal nominal flow rate of 3800 l/min for compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases. Weighing 700 g with G3/8 pneumatic connection 2 and a sub-base pneumatic connection 1, it functions in temperatures ranging from -10 °C to 60 °C with 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.
