Type Rated capacity 1)
TR
1) Rated capacity is based on:
Maximum suction pressure p s
= 70 psig
Suction temperature t s
= 10°F
Condensing temperature t c
= 100°F
Pressure drop across regulator ∆p = 2 psi
Note: The connection dimensions chosen must not be too
small, as gas velocities in excess of 130 ft/s at the inlet
of the regulator can result in flow noise.
