Air Pressure Regulator provides large flow capabilities.
October 26, 2010 -
Available with port sizes of 3/8, ½, ¾, and 1 NPT and BPST, with ¼ NPT gauges, direct-acting Type 78 offers 5 different pressure output ranges up to 125 psig, max supply pressure of 400 psig, and flow rates over 200 scfm. Rolling diaphragm provides low-friction operation, while balanced pintle minimizes output pressure changes caused by fluctuations in supply pressure. Suited for pipe or rail mounting, regulator has die-cast zinc and aluminum housing to withstand harsh environments.

Marsh Bellofram Precision Controls Division Introduces Type 78 High-flow Air Pressure Regulator for Industrial Applications
Newell, West Virginia, USA - The Precision Controls Division (PCD) of Marsh Bellofram Corporation (www.marshbellofram.com), a member of the Marsh Bellofram Group of Companies, has announced the global market introduction of the Type 78, a direct-acting, high-performance air pressure regulator designed to offer high-accuracy, large flow and exhaust capabilities within OEM and industrial applications.
With available port sizes of 3/8, ½, ¾ and 1 NPT and BPST, with ¼ NPT gauges, the Marsh Bellofram Type 78 air pressure regulator is specifically designed for applications that require large flow capabilities and accurate pressure control. Available in five different pressure output ranges of up to 125 psig (8.6 BAR), this precision regulator offers low droop, high accuracy and fine adjustment sensitivity with maximum supply pressure rated at 400 psig (27.6 BAR) and achievable flow rates of well over 200 SCFM. Use of a patented Bellofram rolling diaphragm provides greater sensitivity and improved accuracy, along with low-friction operation and long useful service life. The Type 78 offers a balanced pintle, which minimizes output pressure changes caused by fluctuations in supply pressure. The unit can be either pipe or rail mounted.
Careful design and use of quality materials in manufacturing the Marsh Bellofram Type 78 air pressure regulator ensures long, trouble-free operation. In addition, the rugged die-cast zinc and aluminum housings of the Type 78 are pressure tested to assure safe operation and designed to withstand harsh and abusive environments. This durability is attributed to a chemical conversion coating of all cast components and a vinyl paint finish. Additional optional features and accessories for the Type 78 include low-bleed, non-relieving, square head adjustment, T-handle adjustment, tamper resistant cover, epoxy paint, tapped supply gauge port and tapped exhaust. Mounting brackets and repair kits are also available.
The new Marsh Bellofram Type 78 high-pressure air regulator is ideal for use across a variety of industrial applications, including high-flow actuation; high-flow louvers; slitters, rollers and dewinders; high-flow control loop applications; and calibration loops, among others.
