Application:
The 2 type M-SEW directional valve is a solenoid actuated directional poppet valve. They control the start, stop and direction of a flow.
1. Functions,Section of Poppet Directional Valve M-SEW 6
M-SEW 6 basically consists of a housing (1), the solenoids (2), the hardened valve system (3) and the ball(s) (4) as the closing element.
Basic principle:
In the initial position the ball (4) is pressed onto the seat by the spring(9), and in the switched position by the solenoid (2). The solenoid (2) force acts via the lever (6) and the ball (7) on the actuator pin (8), which is sealed on two sides. The chamber between the two sealing elements is connected with port P. The valve system (3) is thereby pressure balanced with regard to the actuating forces (solenoid or return spring). The valves can, therefore, be used up to a pressure of 63 MPa.
