DESCRIPTION

The Bellofram Type 51 Precision Air Regulator series offers
a high-performance regulator in a compact, low cost pack-
age. It operates in output pressure ranges up to 100 psig /
6.9 BAR (120 psig / 8.3 BAR in T-51FR Corrosive Tec), with
a maximum supply pressure of 250 psi (17.3 BAR).

Materials of construction for standard T-51 Series
Regulators (Non-Corrosive Tec): Die-cast aluminum for the
body and dripwell; glass-reinforced thermoplastic polyester
for the bonnet; acetal resin for the internals; BUNA-N for
the diaphragm, gaskets and O-ring, fluorocarbon for the
pintle seat, and aluminum for the drain valve (plated steel
handle).

Materials of construction for Corrosive Tec T-51FRCT:
Aluminum alloy bonnet, body, and filter bowl, 316
stainless steel internals, Inconel alloy range spring, nitrile
diaphragm (fluorocarbon optional), 316 stainless steel
valve assembly, and painted with an epoxy finish. All
metallic parts for this unit conform to NACE material
requirements #MR-01-75 Class III.

These regulators are available standard (T-51R) or as
filter-regulators (T-51FR & T-51FRCT) and are even
available with an automatic drain, for automated flushing
out of contaminants, (T-51 AFR). These versatile regulators
provide excellent regulation for a wide range of applica-
tions, including pneumatic instruments, controllers,
chucks, and actuators. They can be through-panel
mounted with the supplied mounting nut, bracket-mounted
with the optional bracket or, due to their light weight,
mounted by their ports. The Corrosive Tec is supplied with
a tapped bonnet vent, to allow for the capture of exhaust air.
