Product Introduction：PFT Sleeve Type Choke Valve has a sleeve that throttles the flow on the outside diameter of the ported cage. This choke is used for low capacity/high pressure drop applications. The external sleeve is specifically designed for severely erosive conditions where the combination of high pressure drops and high sand concentrations can reduce the life of a choke.
·Tungsten carbide lined stem and seat provide optimum wear resistance in erosive conditions;
·Metal-to-metal bonnet closure seal;
·Reverse angle trim reduces annular flow-by extending the life of the trim;
·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.
