529003

Pressure regulator manifold LRB-3/8-D-O-K5-MINI

The Festo 529003 is a mini D-series industrial component featuring a directly controlled diaphragm regulator with continuous compressed air supply and a rotary knob with detent for actuator locking. It provides constant output pressure with primary pressure compensation, secondary exhausting, an operating pressure of 1 bar to 16 bar, and a normal nominal flow rate of 1600 l/min across a medium and ambient temperature range of -10 °C to 60 °C. This 1860 g unit accommodates any mounting position with accessories, operates with compressed air as per ISO 8573-1:2010 [7:4:4], and includes a G1/8 pressure gauge setup alongside a regulation range of 0.5 bar to 12 bar.

Why 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.

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
