These Multivalves® are designed for use in single opening ASME containers equipped with a 2 1/2" 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.
With the service valve closed the pressure port will be isolated from the container. This will allow a high pressure leak test to be conducted without disconnecting the pigtail from the service valve.
