Abstract
A non-stick treated valve including a pair of cooperating elastomeric surfaces positioned to engage each other to control fluid flow through the valve. A non-stick coating is applied to the cooperating surfaces to facilitate separation of the surfaces from each other during opening of the valve. The non-stick coating is in the form of an oily substance such as a fluid lubricant for forming a fluid film coating on the cooperating surfaces. In addition, the coating material is formed of a material which is dissimilar from the material forming the cooperating surfaces.
