Seat hydraulic directional control valve 6546382

manual2/2-wayproportional

Directly actuated directional seat valve for liquid media Valve actuation by means of proportional solenoid The proportional solenoid is activated via the Hauhinco automatic control unit „Controller RE4“ The valve seat provides a leak-free seal All parts are made of corrosion-resistant materials, and they are easily replaceable Valve fastening structural plate form with a Hauhinco Connection diagram Function 2/2-way proportional seat valve The generated magnetic force (1) acts via the lever (2), the tappet (3) onto the ball (4) and presses it out of the valve seat (5). This is used to connect lines P and A. The covers (6) support the flange seals from the inside and limits the maximum admissible volume flow. A defined actuating force can be preset (factory setting) by means of the counterspring. The proportional solenoid is electrically activated by regulated current generated as the manipulated variable by the controlled electronic control unit, the Controller RE4. The controlled valve current specifies the degree of opening of the valve, thus, ahydraulic volume flow or pressure control can be performed. Depending on the arrangement of the valve seat (5) and ball (4) the valve will have the basic position normally closed (NC) or normally open (NO).
