Product description
The Plug and Cage Choke moves up and downby rotating the handwheel or under the action of the driver, so as to changethe orifice area of the seat core and achieve the purpose of limiting the flow.The Plug and Cage Choke is generally used in high yield, medium pressure dropconditions; Due to its high flow characteristics, it is generally used in thelater stage of wellhead production.
Features:
01.Tungsten carbide flow plug assembly in conjunction with cage sleeveprovides optimum wear resistance in erosive conditions.
02.Metal-to-metal bonnet closure seal.
03.Thestem bushing moves up and down without rotating to minimize side loading andvibration of the fluid.
04.Self-flushing,pressure-balanced ports minimize stem loads and actuator requirements. Heavyduty thrust bearings also reduce operating torque.
05.Outerflow cage provides protection from impact damage.
06.Stemlock maintains set position.
07.Indicatorcalibrated in 1/64" or multiples of 1/64" increments to showeffective orifice diameter.
