A non-stick treated valve (10) includes a pair of cooperating elastomeric surfaces (16) positioned to engage each other to control flow of fluid through the valve. A non-stick coating depicted by stippling on a surface (36) is applied to the cooperating surfaces (16) to facilitate separation of the surfaces (16) from each other. The non-stick coating is in the form of an oily substance such as a fluid lubricant for forming a film coating on the surfaces (16). In addition, the coating material is formed of a material which is dissimilar from the material forming the cooperating surfaces (16).
Soupape ayant subi un traitement anti-adhérence (10), qui est constituée de deux surfaces d'élastomère en interaction (16) positionnées de manière à pouvoir s'engager l'une dans l'autre pour contrôler l'écoulement de fluide à travers la soupape. Un revêtement anti-adhérent représenté par un pointillé sur une surface (36) est appliqué aux surfaces en interaction (16) pour permettre de les séparer l'une de l'autre. Le revêtement anti-adhérent a l'apparence d'une substance huileuse telle qu'un lubrifiant liquide et est conçu pour former une couche pelliculaire sur les surfaces (16). De plus, la matière de revêtement est différente de la matière dont sont constituées les surfaces en interaction.
