Abstract
Abstract The specification and drawings disclose a valve including a main body having an internal valve chamber connected with first and second flow passages. Cooperating with the first flow passage is a first end fitting which holds the valve member and seats in the main body. The first end fitting is connected to the main body by bolts which extend through it into threaded engagement with the body. Threaded end portions of the bolts extend outwardly of the body adjacent the second passage. A second end fitting cooperates with the second passage and includes openings through which freely pass the threaded end portions of the bolts. Nuts are threaded on the outer end of the bolts to clamp the second end fitting to the main body. This allows the valve to serve as a union since the second end fitting can be removed without disturbing the valve member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
252 words
A valve comprising: a main body-forming portion having first and second ends including a first bore extending inwardly from the first end to define a first flow passage and a valve chamber, a second bore extending inwardly from said second end to define a second flow passage, said second bore being of a smaller diameter than said first bore and aligned therewith to define an internal annular shoulder; a ball valve member positioned in said valve chamber with a first seat member positioned between said ball and said annular shoulder, and a second seat member positioned at the outer end of said first bore; a first end fitting including means for connecting a flow line thereto associated with said first end, said first end fitting adapted to sealingly engage said second seat member; a second end fitting including means for connecting a flow line thereto associated with second end; and, attaching means for releasably connecting said first and second end fittings to said main body, said attaching means including a plurality of bolts extending inwardly through the first end fitting into threaded engagement with said main body, the head portions of said bolts engaging said first end fitting so that tightening of said bolts clamps said first end fitting to said body, said bolts having threaded end portions extending outwardly of said body on said second end and passing freely through said second end fitting, and nut members on said threaded ends for clamping said second end fitting to said main body.
