Abstract
A solenoid valve assembly including a diaphragm assembly which is conformed to the poppet and which moves therewith. The poppet is integral with or mounted to the pole piece of the solenoid. The poppet is shaped to conform to the shape of the valve seat. The diaphragm is preferably elastomeric and stretchable to create a wiping motion against the valve seat when the solenoid is deactivated. The valve seat may also have an annular groove to allow flushing of the valve in both open and closed positions.
