VA-3400

VA-3400 series actuator with easy installation is an electromechanical product, when mounted on VB-3000Q series casting brass valve body or VB-4000Q stainless steel valve body, it can control flow rate in central air-conditioning system, heating system, water treatment or industrial processing industry. This series actuator also can be fitted with other kinds of valve bodies with different connectors.VA-3400 series actuator has 3 basic types:

  • VA-3400 reversible motor operation and provide increasing control;
  • VA-3401 can accept input 0(2)~10V DC or 4~20mA DC control signal and provide proportional control, and also can provide 0~10V DC feedback signal to indicate the position of the actuator;
  • VA-3402 can accept input 0(2)~10V DC or 4~20mA DC control signal and provide proportional control.

Product Feature

  • Low AC voltage synchronic reversible motor.
  • Magnetism clutch.
  • The action uses gear to transit. Output gear rollers are supported by surface rolling bearing, which rotate around the central bearing.
  • Valve working position indicator.
  • Fireproof ABS plastic casing.
  • 0(2)~10V DC or 4~20mA DC control (For VA-3401 and VA-3402 only)
  • Working state (DA or RA) can be selected by jumper.
  • Apply to 13mm, 15mm, 17mm, 19mm or 22mm stroke can be selected by jumper.
  • Have overtime protection function, and failure protection function when without control signal.
  • Have 0~10V DC feedback signal.
  • Have manual open/close valve function (only for VA-34XXM)
  • Have auxiliary micro-switch (only for VA-34XXS)
  • Have manual open/close valve function and auxiliary micro-switch (only for VA-34XXK)
