Abstract
A method for the production of a valve is provided comprising molding a valve body with a first mold, preloading the valve body with a second mold, molding a sealing portion in an open position onto the valve body, and releasing the preloaded valve body. The sealing portion enters a closed position when the preloaded valve body is released. When the valve is in use, the sealing portion opens when under a fluid pressure, and closes when the pressure is released.

A method for the production of a valve comprising:
- molding a first part of a valve with a first material;
- and
- molding a second part of the valve with a second material wherein the first material and the second material are dissimilar materials such that the first and second materials do not bind to each other and wherein the first part in the second part are mechanically bound together at at least one point.
A method for the production of a valve comprising:
- providing a preloaded substantially rigid housing;
- and
- overmolding the preloaded substantially rigid housing with a substantially flexible material wherein the substantially rigid housing is released from its preloaded state after the substantially flexible material is overmolded thereon, the substantially flexible material forming a valve that enters a closed position when overmolded onto the substantially rigid housing.
