Abstract
A valve comprising a valve body having a chamber therein, a knife-edged valve seat in the chamber, and a knife edge in the chamber substantially circumscribing the valve seat. First and second passages are provided in the valve body leading to the chamber with the first passage terminating in a port substantially at the valve seat. A valve member is adapted to engage the valve seat in a first position to block flow through the port and electromagnetic means is energizable to move the valve member off of the valve seat. The valve is constructed and arranged so that the movement of the valve member off of the valve seat is carried out with mechanical advantage.
