Festo
546430
Basic valve LR-D-MINI
The Festo 546430 is a mini series D directly controlled diaphragm regulator featuring a rotary knob with detent for actuator locking and a constant output function with primary pressure compensation and secondary exhausting. Designed with a normal nominal flow rate of 126 cfm, it operates within a pressure range of 1 bar to 16 bar and regulates output pressure between 0.5 bar and 12 bar using compressed air or inert gases. Weighing 10.5 oz with a moderate corrosion resistance class of 2, this component supports front panel mounting, in-line installation, or accessory mounting across a temperature range of 14 °F to 140 °F.

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.
