3/2 way valve B2 x,y externally 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 two function variants , A-T NO and P-T NO
  • The hydraulic control pressure (X, Y) is applied externally via the connection diagram
  • 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 AT 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 . Within the switching phase, the valve is provided with a positive overlap.

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 (9). Thus, the line (T) is shut o and the lines (P, A) are connected. By switching the pilot valve (5), the piston valve area (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 (A, T) are connected and the line (P) is shut off . Within the switching phase, the valve is provided with a positive overlap.

Areas of application

3/2-way valve A-T NO, P-A NOActuation of hydraulic drives (hydraulic cylinder). These valves will particularly be used if due to the medium a separation between the operating and the control circuit is required.
3/2 -way valve P-B NOThe valve works like a hydraulic separator; optionally, it may pass on the supplied pressure and the volume fl ow from line P to line A or B. Thus, optionally pressure can be applied to two different pressure circuits.
