    • Position Transmitter (output 4-20mA or 0-10VDC)
    • Various Local position control options providing easy commissioning and operation in the field.
  • Hard anodized Aluminum casting and external epoxy powder coated against severe industrial environment.
  • Precisely machined double worm gear c/w minimum back-lash, low noise, high output torque.
  • Self-locking feature provided by double worm gearing to keep position of valve unchanged against reverse torque from valve.
  • Sealing By O-ring in all interfaces NEMA 4, 4X, IP67(standard), and double O-ring for IP68 submersible (optional)
  • Different sizes handwheels depending on actuator torque, and includes knob ofor easy operation.
  • Specially designed class F induction motor to generate high starting torque and high efficiency equipped with thermal protector to prevent damage from over heating.
  • Captive cover bolts
    – Designed to prevent losing during maintenance or installation.
    * All external bolts are stainless steel for rust prevention.
  • Removable drive bushing and ISO5211 mounting base
    – (F07~F30) for easy mounting on valves.
  • External mechanical stopper
    – Prevents over-run of travel during manual operation.
  • Torque switches
    – Protect actuator from damage caused by overload from the driven valve over the whole travel. (1 each for open and 1 each for close)
  • Limit switches
    – Directly connected with output shaft for accurate valve position. (2 ea for each travel end (open/close)).
    – Optional Extra Limit Switches (Max 4 ea for each end) : Except for JFE 0100
  • Terminal strip
    – Spring loaded push type terminal for tight wiring connection under severe vibration.
  • Manual override
    – Auto / Manual switchable lever and handwheel engagement for emergency manual operation.
    – Drive force automatically resorted by motor start, unless lever padlocked to prevent this occuring.
