Claims22
1-22. (canceled)
A valve for controlling a passage of a fluid, comprising:
- a. a body having:
- a first bore and a second bore extending inwardly from the exterior of said body and a valve chamber therebetween, a first outlet fluidly connected to said valve chamber, and an inlet fluidly connected to said valve chamber;
- b. a first bonnet connectable to said first bore and having a first opening axially aligned with said first bore;
- c. a second bonnet connectable to said second bore and having a second opening axially aligned with said second bore;
- d. a ball member adapted to be disposed within said valve chamber, said ball member comprising a first passage adapted to allow passage of said fluid between said inlet and said first outlet;
- and
- e. a first actuating stem connectable to said ball member adapted to be located within said first opening of said first bonnet and to control the passage of said fluid between said inlet and said first outlet;
- said valve further comprises:
- a second outlet fluidly connectable to said valve chamber through said second opening of said second bonnet;
- a second passage within said ball member adapted to provide passage of said fluid between said inlet and said second outlet;
- and a second actuating stem adapted to be located within said second opening of said second bonnet and having a controlling end fitted to be received within said second bore, so as to control the passage of said fluid between said second outlet and said inlet;
- wherein said first and second bores are axially aligned, and said first and second actuating stems are positioned opposite in an in-line manner.

A method of manufacturing a valve, comprising steps of:
- a. providing a body having:
- a first bore and a second bore extending inwardly from the exterior of said body and defining a valve chamber therebetween, a first outlet fluidly connected to said valve chamber, and an inlet fluidly connected to said valve chamber;
- b. disposing a ball member within said valve chamber, said ball member comprising a first passage adapted to allow passage of said fluid between said inlet and said first outlet;
- c. connecting a first bonnet having a first opening to said first bore, such that said first bonnet being axially aligned with said first bore;
- d. connecting a second bonnet having a second opening to said second, such that said second bonnet being axially aligned with said second bore;
- e. connecting a first actuating stem to said ball member, said first actuating stem being adapted to be threaded within said first opening of said first bonnet and to control the passage of said fluid between said inlet and said first outlet;
- f. providing a body having a second outlet connectable to said valve chamber through said second bonnet;
- g. providing a second passage within said ball member adapted to provide passage of said fluid between said inlet and said second outlet;
- h. connecting a second actuating stem to said second bonnet by inserting said second actuating stem to said second opening of said second bonnet, said second actuating stem having a controlling stem fitted to be received within said second bore, so as to control the passage of said fluid between said inlet and said second outlet;
- wherein said first and second bores are axially aligned, and said first and second actuating stems are positioned opposite in an in-line manner.
