2-way regulating valve for dynamic hydronic balancing, PN 25, Valveco compact

How energy efficiency is improved

Automatic dynamic hydronic balancing with the SAUTER Valveco compact regulating valve supplies downstream consumers correctly and reduces temperature variations in the room so that energy is used more accurately and more efficiently


  • Dynamic volume flow control in closed water circuits in conjunction with AXF 217S, AXM 217(S), AXS 315S and AXT 301, 311 actuators for unit valves

  • Volume flow range 30…11,500 l/h

  • Simple presetting of maximum required volume flow

  • Automatic flow regulation

  • Versions with and without pressure measurement nipple

  • The valve is closed when the spindle is moved in

  • Closes against the pressure

  • Differential pressure across the control unit is kept constant; valve authority 1

  • Slight adaptation of the proven SAUTER actuator technology

  • VDL 010…032: Valve with male thread, flat-sealing.

    Valve body and plug made of dezincification-resistant (DZR) brass

  • VDL 040 and 050: Valve with female thread.

    Valve body made of cast iron with spheroidal graphite (GJS-400)

  • Spindle made of stainless steel

  • Temperature range of medium: 0…120 °C
