2/2-way control valve C3 proportional actuated DN25-DN100 PN500

  • Operating pressure: 500bar
  • Nominal size(s): DN25, 32, 40, 50, 65, 80, 100
  • Ways: 2/2

Features

  • Hydraulically actuated directional seat valve for liquid media
  • Actively controllable 2-way control valve with a position controlled piston position
  • The controlled piston position specifi es the variably adjustable fl ow cross-section
  • The valve is actuated via proportional 2-way pilot valves
  • The pilot valves are activated via the digital Controller RE4
  • Valve pistons are sealed via seals within the body, thus no inner leakages develop
  • Valve fastening structural plate form with a Hauhinco connection diagram
  • Optionally, the valve position can be monitored by a proximity switch

Function

The pilot valves (5, 6) and the control pcb (8) form the pilot control group of the 2-way control valve. 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 (4) is depressurised by the activated pilot valve (5). Thus, the lines (A, B) are separated. Activated by the pilot valve (6), the opening area (4) is pressurised and the valve piston (2) lifts o the valve seat (3). The pilot valves (5, 6) are activated according to the controller specifi cation, thus, the valve piston (2) moves into the requested position. The fl ow cross-section is set analogue to the valve‘s piston position. Both proportional pilot valves are 2-way seat valves NC. As soon as the control is switched off, the 2-way control valve remains in the position reached last. If an S/W pilot valve NO (7) is added to the proportional pilot control group, the 2-way control valve is moved into the safe basic position with the control switched off. Pilot valves (5, 6, 7) are fastened to the valve body (1) via the control pcb (8). The basic valve position can also be monitored by a limit switch (9).
