Definitions

  • Control valves of this type have the advantage that they close absolutely tight and are largely balanced. That is why they are suitable for quick actuation using appropriately designed electromagnets.
  • the control valve consists of a control valve sleeve (1) in which a rotationally symmetrical control valve body (2) is sealingly guided.
  • the guidance is effected by a high-pressure guide part (6) and a low-pressure guide part (7).
  • the high-pressure guide part (6) has the diameter of the control valve seat (3), the diameter of the low-pressure guide part (7) is smaller according to the width of the control valve seat.
