Abstract
A valve assembly for controlling the flow of fluid, has a passage for fluid flow therein and open and closed positions whereby fluid flow through said passage is respectively allowed and prevented. First and second mating surfaces define a contact area therebetween when the valve assembly is in its closed position. Relief means is provided for communicating fluid from the passage with an inner portion of the contact area for operably reducing a force required to disengage the mating surfaces and open the valve assembly.
