  • Linear unit, suitable for all ..Max-..-F actuators size S or M

Valve adaptation / neccessary accessories

  • To select the right valve adaptation and get the right price information
    the following data are required:

    1. Valve manufacturer
    2. Valve type
    3. Valve nominal size (diameter) DN

  • For adaptations which are still designed by Schischek this data are minimum requirements
  • To design new adaptations we need additional details of the valve body
    as well as drawings
  • At purchase order you have to order both parts – actuator + adaptation
