ABSTRACT:
The invention relates to a pilot controlled, magnetic type of valve having a diaphragm with the outer edge floatably attached to the housing. Excessive deformation of the diaphragm is prevented by providing a supporting ring which is axially movable in relation to the body of the valve and has a conical surface which is engaged by the diaphragm and to which the diaphragm conforms when the valve is in an open position.
