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. The flow cone is mechanically coupled to the stem so that the inner sidewall of the flow cone may travel along the second outer sidewall of the flow nozzle. The flow cone presses a seal against the nozzle ledge in order to mechanically set the seal.
