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.

Areas of application | |
| 3/2-way valve A-T NO, P-A NO | Actuation 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 NO | The 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. |
Included in the scope of supply | |
| Mounting screws of the valve | Cheese-head screw |
| Cable socket of the valve solenoid - Supply voltage 24 VDC | according to DIN 43650 – type of design A max. 100 VA |
