ABSTRACT OF THE DISCLOSURE An improved compression type valve for a fire hydrant or the like includes an improved resilient valve member for sealingly engaging a seating ring in order to control the passage of fluid through the valve. The improved valve member is provided with a first bevel extending from a side surface thereof toward the top surface of the valve member, and with a second bevel which extends from the first bevel to the top surface. The second bevel prevents pressure which is applied to the valve element from causing the top surface of the valve element to deform around its circumference and break off, as was the case with prior art valve members of this type.
