available port sizes of â…œ, Â½, Â¾ and 1 NPT
and BPST, with Â¼ 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. 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.
rugged die-cast zinc and aluminum housings of the Type 78 are pressure tested
for 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.
Type 78 high-pressure air regulator can be used for use across for industrial
applications, including high-flow actuation; high-flow louvers; slitters,
rollers and dewinders; high-flow control loop applications; and calibration
