label: Description
content: This model represents a valve chest and drop cut-off valve of the Sickels type in which an adjustable cam operates the catch during the opening movement of the valve so that the valve may be released as near the beginning of the closing movement as is desired. In the earlier cut-offs the catch was operated by the closing movement alone, and the valve could not be tripped until sufficient closing movement had taken place to operate the whole extent of the catch.
