2/2 way valve C3 xyz actuated DN80-DN150 PN320 (two stage pilot control)

  • Operating pressure: 320bar
  • Nominal size(s): DN80, 100, 125, 150
  • Ways: 2/2

Features

  • Hydraulically actuated directional seat valve controlling liquid media.
  • Actively controllable 2/2-way valve with a 3-stage control logic provides safe opening and closing
  • The valve is actuated via a 3/2-way pilot valve
  • Function variants possible via the interconnection of the Z-line
  • Valve piston and seat are coupled and close hydraulically „leak-free“.
  • Valve pistons are sealed via seals within the body, thus no inner leakages develop
  • The valve cross-section can be set via the stroke limitation and be locked mechanically
  • Valve fastening structural plate form with a Hauhinco connection diagram
  • Optically and with an optional proximity switch, the valve position can be monitored
  • Optionally, a locking device can be selected for the stroke limitation

Function

The valve piston (2) guided within the valve body (1) is pressed into the valve seat (3) by the hydraulic power generated by the control pressure (X) on the closing area (5), provided the opening area (6) is depressurised by the pilot valve (4). Thus, the lines (A, B) are separated. By switching the pilot valve (4), also the opening area (6) of the valve piston (2) is pressurised and lifts off the valve seat (3), the valve piston (2) moves into the opened position up to the mechanical end position and to the stroke limitation (7). Thus, the lines (A, B) are connected. Control channel (Z) is assigned to the closing area and control channel (X) to the opening area. The valve can be opened and closed actively by means of control pressure (X, Y), independent of the pressure along the work lines (A, B). The area ratios „opening area/closing area“ and „closing area/cable area (A, B)“, ensure a safe opening and closing of the valve. Depending on the design of the pilot valve (4), the basic valve position normally closed (NC) or normally open (NO) is provided. The position of the valve piston (2) can be monitored by the proximity switch (8).
