Type 1290
Specifications
This section lists the specifications for the Type 1290 vapor recovery regulator. Specifications for a given regulator as it
originally comes from the factory are stamped on the regulator nameplate located on the actuator, while the pilot control
spring range appears on the pilot spring case nameplate.
