Type 78 - T78 High Flow Regulator
The Type 78 regulator is specifically designed
for applications that require large flow capability and accurate pressure control. This regulator
offers low droop, high accuracy, and fine
adjustment sensitivity. The use of a Bellofram
rolling diaphragm provides greater sensitivity
and improved accuracy. The Type 78 offers a
balanced pintle, which minimizes output pressure changes caused by fluctuations in supply
pressure. Careful design and quality materials
throughout assure long, trouble-free operation. The rugged die-cast zinc and aluminum
housings are pressure tested to assure safe
operation, and are 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.
With a maximum supply pressure of up to 400
psig/27.6 BAR and output ranges up to 125
psig/8.6 BAR, the Type 78 can achieve flow
rates of well over 200 SCFM. It can be panel or
pipe mounted.
