3/2 way valve B2 x,y internally actuated DN10-DN16 PN320

  • Operating pressure: 320bar
  • Nominal size(s): DN10, 16
  • Ways: 3/2

Features

  • Hydraulically actuated directional seat valve controlling liquid media.
  • Passively controllable 3/2-way valve with 2-stage control logic
  • The basic valve position is maintained by the hydraulic pressure (P)
  • The valve is designed in the function variant P->T NO, the function variant A->T NO can be generated by a pilot valve with the hydraulic function P->A NO
  • The hydraulic control pressure (X, Y) is picked off internally along the lines (P, T)
  • Valve piston and valve seat are coupled and close hydraulically „leak-free“
  • The valve is actuated hydraulically via a 3/2-way pilot valve
  • Valve fastening structural plate form with a Hauhinco connection diagram

Function of 3/2-way valve PA NO

The valve piston (2) guided within the valve body (1) is pressed into the valve seat (3) by the hydraulic power and the spring force (7) generated by the operating pressure (P) on the control surface (6). Thus, the line (P) is shut o and the lines (A, T) are connected. By switching the pilot valve (5), the control surface (8) is pressurised and the valve piston (2) is moved into the actuated position. Thus, the valve piston (2) is pressed into the valve seat (4), the lines (P, A) are connected and the line (T) shut off.

Function of 3/2-way valve AT NO

The valve piston (2) guided within the valve body (1) is pressed into the valve seat (4) by the hydraulic power generated by the control pressure (X) on the control surface (8), against the operating pressure (P) on the control surface (9) and the spring force (7). Thus, the line (P) is shut o and the lines (A, T) are connected. By switching the pilot valve (5), the piston valve area (8) is depressurised and the valve piston (2) is moved by the operating pressure (P) into the non-actuated position. Thus, the valve piston (2) is pressed into the valve seat (3), the lines (P, A) are connected and the line (T) is shut off.
