Flow Control DivisionAccutronix MXLimitorque satisfies today's needs for valve actuation formany industries from Nuclear Power to Water Treatment.LimitorqueMaking valve control easier

Flow Control DivisionAccutronix MXThis GS-350 actuator was installed atPearl Harbor in 1941 and removed fromservice in June of 2012. It was one ofmany GS actuators controlling the drydocks.Over 70 years of service and still workingwhen removed.Yes, they were there, on that day.LimitorqueMaking valve control easier

Flow Control DivisionAccutronix MXValve Applications for ActuatorsLimitorqueMaking valve control easier

Flow Control DivisionAccutronix MXApplications: Linear Multi-Turn Gate Valve Globe ValesRising Stem :Gate require the actuator tosupport the Thrust Load of the gate. Stembushings are threaded to match gate stem.Non-Rising Stem /Keyed shaft Applications :Gate of Gear Drives- the actuatoronly provides torque.LimitorqueMaking valve control easier

Flow Control DivisionAccutronix MXActuator SizingStem Thread TerminologyPitch is the number of threads linearlyalong the stem. Expressed as afraction (distance in inches/number ofthreads)Common Valve Stem Threads P/L’s¼P–¼L¼P-½L1/3P -1/3L1/3P - 2/3L2/5P –2/5L 4T/inch 2T/inch 3T/ inch 1.5T/inch 2.5 T/inchLead is the number of revolutions orturns around the stem for anincrement of travel in inches.Expressed as a fraction (increment oftravel/turns)LimitorqueMaking valve control easier

Flow Control DivisionAccutronix MXActuator Thrust ApplicationsThrust (Multi-Turn Valves)For Gates, Globes, or Sluice Gates, the thrustcan be calculated from the pressure and valvedata.Thrust and Torque Ratings must be consideredwhen sizing.Valve threaded stem must not exceed thrustbase limitations.Don’t plan on using tubing brackets for thrustapplication – Thrust loads will make thempancakes – Or crack the floorLimitorqueMaking valve control easier

Flow Control DivisionL120 85 and Smaller andAll MX units use a (A1)Thrust base for all thrustapplications.Accutronix MXL120-190 and LargerAll V and S gears use Top Entrystem nut for Thrust ApplicationsLimitorqueMaking valve control easier

Flow Control DivisionAccutronix MXGlobe Valve –Rising Rotating ApplicationActuation is by driving the valve stemwith TORQUE and allowing it to riseas it rotates inside the actuator.Splined, double keyed or hexedbushing are normally attached to thevalve stem with a mating drive in theactuator.Must provide enough travel room in theactuator’s drive sleeve to allow fullLimitorquevalve travel.Making valve control easier

Accutronix MXFlow Control Division Making Valve Control Easier Application: Quarter Turn ValvesActuators provide torque to stroke andseat valves and travel limits to preventvalves from being driven past theseating area. Butterfly BallActuator connects to valvestem with keyed or stem flats.Speeds: 30 -120 Secondsare common.LimitorqueMaking valve control easier

Flow Control DivisionAccutronix MXValve Seating MethodsLimitorqueMaking valve control easier

Flow Control DivisionAccutronix MXValve Seating OptionsTorque Seating: Motor turned off by Torque Switch when force is reached.Limit Switch is used to turn on /off position lights or indicationTorque Switch also provide protection in travel.** Locking Gearing required on Electro-Mech Actuators but notrequired on MX. (Torque Hammer)Position Seating: Motor turned off by Limit Switch when closed POSITION isreached. Limit Switch is used to turn on /off position lights or indication. Torque Switch is protection. Locking Gearing is not require on MOST application.LimitorqueMaking valve control easier

Flow Control DivisionAccutronix MXThe Reversing Starter is the heart of MOV controls.It’s either in the actuator (Integral) or in the plantssystems (NCU)- It drives the motor open or close based oncontrol power.- It turns the motor off when control power isinterrupted by LS/TS, Motor Thermal.-It is electrically and mechanically interlocked sothe motor can not be powered in both directions atthe same time.LimitorqueMaking valve control easier
