Festo
528956
Pressure regulator manifold LRB-3/8-D-7-O-K2-MIDI
The Festo 528956 is a Midi size D series directly controlled diaphragm regulator featuring a continuous compressed air supply and a rotary knob with detent actuator lock. It provides constant output pressure with primary pressure compensation and secondary exhausting across a regulation range of 0.5 bar to 7 bar (7.25 psi to 101.5 psi) within an operating pressure of 1 bar to 16 bar. This component supports a normal nominal flow rate of 3800 l/min using compressed air as per ISO 8573-1:2010 [7:4:4] and operates in medium and ambient temperatures from -10 °C to 60 °C.

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.
