Festo
194674
Pressure regulator LRS-3/4-D-DI-MAXI
The Festo part number 194674 is a Maxi-size Series D directly controlled diaphragm regulator featuring a rotary knob with detent actuator lock and an integrated pressure gauge. It delivers a normal nominal flow rate of 6800 l/min across an operating pressure range of 1 bar to 16 bar and a regulation range of 0.5 bar to 12 bar, accommodating compressed air and inert gases within a temperature span of -10 °C to 60 °C. Designed with secondary exhausting, primary pressure compensation, and return flow characteristics, this 1680 g component supports front panel mounting, in-line installation, or accessory mounting with moderate corrosion stress resistance.

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.
