Introduction
Scope of the Manual
This manual provides installation, adjustment and
maintenance procedures and also parts ordering
information for Type 1290 Vapor Recovery regulator
complete with a Type EGR main valve, a Type T208P
or T208PL pilot and a Type MR95H supply pressure
regulator. Detailed instructions for installation,
adjustment and maintenance of other equipment used
with this regulator are found in separate manuals.
Product Description
The Type 1290 vapor recovery regulator is a self-
contained, pilot-operated regulator system used for
vapor recovery of blanketing gas. When blanketing gas
pressure inside the vessel rises due to thermal heating
or pump-in operations, the Type 1290 regulator senses
an increase in vessel pressure and vents excessive
internal tank pressure to a vapor recovery storage tank.
