Claim 4

The valve of claim 2 wherein the length of the ring is substantially equal to the length of said bore to engage said flanges and thereby support the valve member when the valve is assembled.

Claim 5

The valve of claim 2 wherein the length of the ring is less than the length of said bore, and characterized further to include a support ring in at least one end of said bore engaging one end of the bearing ring and the flange at the respective end of the valve body for supporting the valve member when the valve is assembled.

Claim 6

The valve of claim 4 characterized further to include a second support ring in the opposite end of said bore engaging the opposite end of the bearing ring and the remaining flange when the valve is assembled.

Claim 7

The valve of claim 2 characterized further to include a bearing sleeve in each aperture of the ring of a size to journal the respective valve stem therein.

Claim 8

The valve of claim 1 wherein the tongue is formed on the outer end of the second valve stem and the mating slot is formed in the inner end of the first valve stem.

Claim 9

The valve of claim 3 characterized further to include seal means on the ring sealingly engaging the second and third valve stems and the flanges when installed in the valve body to isolate the body from fluid controlled by the valve.

Claim 10

The valve of claim 1 wherein the first valve stem has an annular shoulder thereon facing away from the bore in the valve body and a mating annular shoulder in the valve body to provide a metal-to-metal seal of the first valve stem in the body.

Claim 11

The valve of claim 2 wherein the valve member is a disc having an annular seating surface aligned with the second and third valve stems, and a seat is carried by the ring sealingly engaging the seating surface on the disc when the valve is closed.

Claim 12

The valve of claim 1 wherein the valve member is a disc having an annular seating surface offset from the second and third valve stems, and characterized further to include a valve seat of a size to be positioned in said bore between one end face of the valve body and the bearing means to sealingly engage the seating surface in one position of the disc.

Claim 13

The valve of claim 11 characterized further to include a second valve seat of a size to be positioned in said bore between the bearing means and the opposite end face of the valve body to sealingly engage the seating surface of the disc in a second position of the disc.

Claim 14

A valve assembly between a pair of flanges, comprising: a valve body having opposite end faces shaped to mate with said flanges, a bore therethrough intersecting said end faces, and an aperture extending transversely therethrough intersecting said bore; a first valve stem journaled in said aperture; means securing the first valve stem in a position such that the inner end thereof is substantially coterminous with the wall of said bore; a valve member having diametrically opposed second and third stems thereon, the length of the valve member and stems generally between the outermost end portions of the second and third valve stems, being greater than the diameter formed by the bore through the valve body; the outer end of the second valve stem and the inner end of the first valve stem being shaped to provide a mating tongue and groove; said valve member and second and third valve stems being of a size such that the valve member may be tilted at an angle to the axis of said bore for partial connection of the first and second valve stems and then rocked into the valve body with the valve member and third valve stem positioned in said bore; A bearing sleeve journaled on each of the second and third valve stems the bearing means being insertably disposed in the housing bore, the portion of the second and third valve stems journaly engaged by the bearing means being disposed generally within the housing bore; means adapted to be positioned in said bore for supporting said bearing sleeves and preventing movement of the valve member axially in said bore when the valve is assembled.

Claim 15

A valve assembly between a pair of flanges, comprising: a valve body having opposite end faces shaped to mate with said flanges, a bore therethrough intersecting said end faces, and an aperture extending transversely therethrough intersecting said bore; a first valve stem journaled in said aperture; means securing the first valve stem in a position such that the inner end thereof is substantially coterminous with the wall of said bore; a valve member having diametrically opposed second and third stems thereon, the length of the valve member and stems generally between the outermost end portions of the second and third valve stems, being greater than the diameter formed by the bore through the valve body; the outer end of the second valve stem and the inner end of the first valve stem being shaped to provide a mating tongue and groove; said valve member and second and third valve stems being of a size such that the valve member may be tilted at an angle to the axis of said bore for partial connection of the first and second valve stems and then rocked into the valve body with the valve member and third valve stem positioned in said bore; A bearing sleeve journaled on each of the second and third valve stems the bearing means being insertably disposed in the housing bore, the portion of the second and third valve stems journaly engaged by the bearing means being disposed generally within the housing bore; means adapted to be positioned in said bore for supporting said bearing sleeves and preventing movement of the valve member axially in said bore when the valve is assembled.

Claim 16

The valve of claim 13 wherein said last-mentioned means includes a support ring between one end face of the valve body and said bearing sleeves having an outer diameter substantially corresponding to the diameter of said bore, a pair of partial apertures in one end thereof arranged to receive portions of said bearing sleeves, and an opposite end shaped and arranged to be engaged by the respective flanges.

Claim 17

The valve of claim 14 characterized further to include a second support ring extending from the opposite end face of the valve body and the first-mentioned support ring having an outer diameter substantially corresponding to the diameter of said bore, a pair of partial apertures in one end thereof arranged to receive portions of said bearing sleeves, and an opposite end shaped and arranged to be engaged by the respective flange.

Claim 18

The valve of claim 15 wherein the valve member has a pair of annular seating surfaces thereon arranged in spaced relation to mate with said support rings in one position of the valve member, and wherein each support ring has an annular seating surface thereon mating with the respective seating surface on the valve member when the valve member is in said one position.

Claim 19

The valve of claim 16 wherein the valve member has a port opening therethrough between the seating surfaces on the valve member.
