The Marsh Bellofram 41-1 Precision Air Regulator comes standard with 1⁄4 NPT ports and a knob, and can be panel mounted using either the center nut or the threaded shoulder holes, spaced 1.5 in. (38.1 mm) center-to-center.
The Type 41 Precision Air Pressure Regulator incorporates a patented Bellofram rolling diaphragm construction and is perfect for applications which require high flow capacity, low droop, high accuracy and fine adjustment sensitivity. The 41-1 regulator offers a smaller size and several mounting options, allowing it to be used as compact drop-in replacements for other manufacturers’ models.
The durable design and construction of the Type 41 incorporates precision cast aluminum housings which are finished with vinyl paint to resist scratches, weathering and other challenging environmental conditions. Use of quality materials ensures long, hassle-free operation. All units are pressure tested and chromate treated for internal corrosion resistance. A rubberized, soft-seat valve stem provides stability and “forgives” dirt and other foreign matter. An aspirator maintains downstream pressure and compensates for droop when high flow occurs. The gauge port is convenient for gauge installation and can also be used as an additional full flow outlet.
