Abstract: The present invention is an ajustable valve which includes a T-shaped fitting with a first bore, a stem, a bonnet and a valve mechanism with an outlet, a flow nozzle and a flow cone. The outlet is a cylinder with a bore of a first diameter. The outlet has a nozzle ledge and is fixedly coupled to the first bore. The flow nozzle is a cylinder with an inner sidewall and has a first open end and a second closed end. The flow nozzle has a first outer sidewall of the first diameter adjacent to the first open end and a second outer sidewall of a second diameter which is larger than the first diameter adjacent to the second closed end. The flow nozzle is slidably engaged within the outlet. The second outer sidewall has a plurality of orifices extending therethrough and communcating with the inner sidewall of the flow nozzle. The flow cone is a cylinder having an inner sidewall which slidably engages around the second outer sidewall of the flow nozzle.

Abstract: The invention is an improvement for controlling the flow of fluid in a conduit to be used in combination with a ball valve. The ball valve includes a valve body which has a bore extending therethrough and which also has an inlet and an outlet which are axially aligned and adapted to be mechanically coupled to the conduit. The valve body also has an aperture therein. The ball valve also includes a spherical valve member having a port the axis of which is alignable with the axis of the bore of the valve body and a stem having an inner end mechanically coupled to the spherical valve member and an axially outer end which extends through the aperture of the valve body. The ball valve further includes a device for forming a seal between the aperture of the valve body and the stem.
