New Original Siemens SAS61.03 Electric Valve Actuator<\/h1>\n

Product Overview<\/h2>\n

This is an original Siemens ACVATIX SAS61.03 non\u2011spring\u2011return electromotoric stroke valve actuator, delivering 400\u202fN positioning force with 5.5\u202fmm nominal strokehit.sbt.si…. It runs on AC\/DC\u202f24\u202fV power supply and accepts 0\u201110\u202fV DC or 4\u201120\u202fmA modulating control signals, meanwhile providing 0\u201110\u202fV DC position feedback signal. It directly mounts on Siemens VVG44, VXG44, VVG55 series 2\u2011port and 3\u2011port modulating valves, widely used in HVAC heating, cooling, chilled\u2011water and hot\u2011water circulation systems for building automation, heat\u2011exchange stations and air\u2011handling unit water\u2011loop flow regulationdocs.rs-on…. No spring\u2011return function; the actuator stays in\u2011place upon power loss.<\/p>\n

Main Functions<\/h2>\n
    \n
  1. Proportional modulating drive for linear\u2011stroke control valves, continuously adjust valve opening according to analog control signal.<\/li>\n

  3. Built\u2011in manual override knob for manual valve position adjustment during commissioning, debugging or maintenance.<\/li>\n
  4. Visual position indicator shows current valve opening status on\u2011site.<\/li>\n
  5. Support optional auxiliary switch ASC10.51 for additional limit\u2011position signal output.<\/li>\n
  6. Tool\u2011free direct mounting for matched valve bodies; compatible with legacy valves by using ASK30 adapter kithit.sbt.si<\/li>\n
  7. Parallel multi\u2011actuator driving is available for multi\u2011valve synchronous control within system design limits.<\/li>\n<\/ol>\n

    Technical Features<\/h2>\n
