ASME Multivalves® for Vapor Withdrawal G8475RL Series
Valves with Presto-Tap PG8475, PT7556 Series Valves
Application
These Multivalves® are designed for use in single opening ASME
containers equipped with a 2½” M. NPT riser. They can be used
with underground ASME containers up to 639 sq. ft. surface area,
and above ground ASME containers up to 192 sq. ft. surface area. A
separate opening is required for liquid withdrawal. The MultiBonnet®
is standard on this valve.
Features
• The most complete Multivalve® assembly in the LP-Gas industry.
• Combines low emission double back check filler valve, vapor
equalizing valve, pressure relief valve, service valve, fixed liquid
level gauge, “junior” sized float gauge flange opening and a
plugged pressure gauge opening.
• Double back check filler valve is low emission, 2.13cc at
disconnection with no reduction in fill rates.
• Designed for installation of a ⅛” FNPT pressure gauge
or pressure gauge connection. The pressure test port will
communicate to the downstream side of the service valve.
PG8575RL
• PG8475RL Version: With the service valve closed the
pressure test/Presto-Tap® port is isolated from the container. Reduced area above
This will allow a high pressure leak test to be conducted without the seat and unique
disconnecting the pigtail from the service valve. For more seat disc design
information see page C12.
• Vapor equalizing valve with excess flow has increased capacity
matched to the filler valve.
