Electromagnetic flow control valve

The valve includes a body (1) with an input (2), output (3) and valve seating (4). A coil (6) surrounds a fixed core, whilst a mobile core (10) defines an air gap with the fixed core and carries the valve stem (12) which is held against the seating by a spring. A membrane (14) closes the space betwe...

More Information
Summary:The valve includes a body (1) with an input (2), output (3) and valve seating (4). A coil (6) surrounds a fixed core, whilst a mobile core (10) defines an air gap with the fixed core and carries the valve stem (12) which is held against the seating by a spring. A membrane (14) closes the space between the mobile core and the inside of the coil. In order to balance the valve in the open position, the valve includes an axial passage (24) through the fixed hub (9) and a lateral conduit (25, 26) linking the downstream region of the valve with the top of the valve (27). A vibrating membrane (33) fits between the axial passage and the lateral conduit.
