Product Introduction：PFT Plug Type Choke Valve moves up and down by rotating the handwheel or under the action of the driver, so as to change the 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 drop conditions; Due to its high flow characteristics, it is generally used in the later stage of wellhead production.
·Tungsten carbide flow plug assembly in conjunction with cage sleeve provides optimum wear resistance in erosive conditions;
·Metal-to-metal bonnet closure seal;
·The stem bushing moves up and down without rotating to minimize side loading and vibration of the fluid;
·Self-flushing,pressure-balanced ports minimize stem loads and actuator requirements;
·Heavy duty thrust bearings also reduce operating torque;
·Outer flow cage provides protection from impact damage;
·Stem lock maintains set position;
·Indicator calibrated in multiples of 1/64"increments to show effective orifice diameter.
