Festo
194663
Pressure regulator LRS-3/4-D-7-O-MAXI
The Festo 194663 is a Maxi-size Series D pilot-controlled piston control valve featuring a rotary knob with an integrated lock and a constant output pressure function with secondary exhausting. It operates within a pressure range of 0 bar to 16 bar and a regulation range of 0.5 bar to 7 bar, delivering a normal nominal flow rate of 12000 l/min using compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases. Weighing 1215 g with a CRC rating of 2, this component supports front panel mounting, in-line installation, or accessory mounting across ambient and medium temperatures of -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.
