Y695A Series Vapor Recovery Regulators
Features
•  Precision Control—Large diaphragm area
provides very accurate throttling control at low
pressure settings.
 • Easy Conversion—Changes easily from the
Type Y695A to the Type Y695AM with two O-rings
and a machine screw.
•  Rugged Construction—Heavy duty casings and
internal parts are designed to reduce vibration and
shock and give this regulator the ability to
withstand 150 psig (10,3 bar) inlet pressure with
no internal parts damage.
•  Simplicity—Direct-operated, straightforward stem
and lever design minimizes the number of parts
while providing excellent regulation of pressure.
Introduction
The Y695A Series are direct-operated vapor recovery
regulators. These regulators are used to sense an
increase in vessel pressure and vent excessive internal
tank pressure to an appropriate vapor recovery disposal
or reclamation system. They may also be used as
backpressure regulators or relief valves.
