Festo
529990
Pressure regulator MS6-LR-1/2-D5-AS-Z
The Festo 529990 is an industrial MS series size 6 directly-controlled diaphragm regulator featuring a rotary knob with lock actuator and a built-in pressure gauge with a G1/2 pneumatic connection port. Engineered to deliver a constant output pressure with initial pressure compensation and secondary exhaust, it operates within a working pressure range of 0.8 to 20 bar and a pressure control range of 0.3 to 4 bar, achieving a standard nominal flow rate of 7,500 l/min for compressed air and inert gases. This 730 g component supports any assembly position alongside optional front panel, line, or accessory mounting, and functions within a temperature range of -10 to 60 °C with a maximum pressure hysteresis of 0.25 bar.

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.
