Festo
529476
Pressure regulator MS4-LRB-1/4-D5-VS-AS-Z
The Festo part number 529476 is an industrial component of series MS in size 4, featuring a directly-controlled diaphragm regulator design with a looped-through compressed air supply and a rotary knob actuator lock that is lockable with accessories. This component delivers a standard nominal flow rate of 1,900 l/min across a working pressure range of 0.8 to 14 bar and a pressure control range of 0.3 to 4 bar, maintaining a constant output pressure with secondary exhaust and return flow. Weighing 222 g with CRC 2 corrosion resistance, it operates with compressed air according to ISO8573-1:2010 [7:4:4] or inert gases within a temperature range of -10 to 60 °C, and includes copper- and PTFE-free materials that conform to RoHS.
