Pressure regulator MS4-LR-1/8-D7-PAGN-AS-WR

The Festo size 4 industrial component from the MS series is a directly controlled diaphragm regulator featuring a constant output pressure, secondary exhausting, and a return flow characteristic. Operating within a pressure range of 0.8 bar to 14 bar and providing a normal nominal flow rate of 1000 l/min, this unit utilizes a rotary knob actuator lock with detent that can be closed with accessories. It accommodates compressed air per ISO 8573-1:2010 [7:4:4] or inert gases, maintains a moderate corrosion stress rating of CRC 2, and weighs 225 g with flexible mounting options including in-line installation, front panel mounting, or use with accessories.

Why 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.
