Festo
197535
Pressure regulator LRB-D-O-MINI
The Festo 197535 is a mini series D directly controlled diaphragm regulator featuring a continuous compressed air supply and a rotary knob actuator lock with detent. Operating within a pressure regulation range of 0.5 bar to 12 bar and a maximum operating pressure of 1.6 MPa, this component delivers a normal nominal flow rate of 1600 l/min for compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases. It weighs 250 g, supports any mounting position via sub-base and G1/4 pneumatic connections, and includes a G1/8 pressure gauge setup alongside primary pressure compensation and secondary exhausting functions.

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.
