High Flow Relay features 1:1 ratio.

Press Release Summary:



Type 79 relay uses rolling-diaphragm technology and pilot pressure to control output pressure over range of flow and supply variations. Supply and output ports are available in 3/8, ½, ¾, and 1 in. NPT. Pilot and output gauge ports are ¼ in. NPT. Low-bleed and non-relieving versions are available, as well as tapped exhaust, supply gauge port, and external corrosive-resistant epoxy paint. T79 can be used with supplies up to 400 psig and output range of 0-200 psig.

Marsh Bellofram's New High Flow Relay with 200+ SCFM Type 79


Marsh Bellofram has enhanced the technology of their Type 75 air-piloted relay to produce a 1:1 ratio relay with significantly more flow and exhaust capabilities. The Type 79 utilizes Marsh
Bellofram's patented long-life rolling-diaphragm technology. The T79 uses pilot pressure to accurately control output pressure over a wide range of flow and supply pressure variation.

Supply and output ports are available in 3/8", 1/2", 3/4", and 1 I' NPT. The pilot and output gauge ports are 1/4" NPT. Low-bleed and non-relieving versions of the T79 are available, as well as
options for tapped exhaust, supply gauge port, and external corrosive-resistant epoxy paint. Mounting brackets, gauge kits, and repair kits are also available. The T79 can be used with
supplies up to 400 psig and a output range of 0-200 psig. In addition to standalone use, the T79 can be used as a volume booster with any of Marsh Bellofram's T3000 electropneumatic
regulators. It is also an integral component of the new compact high-flow SPC3R electropneumatic regulator.

Bellofram is a world leader in producing precision pneumatic control instrumentation. With a product line that includes Pressure Regulators, I/P and E/P Transducers and Air Cylinders. Bellofram is able to meet any pneumatic or electropneumatic control application.

Founded in 1953, Bellofram has built its reputation on
originating and manufacturing innovative quality products.
