Abstract
A poppet assembly for a valve can include a valve stem for cooperating with a valve actuator, a first valve member coupled to the valve stem in a fixed position and configured to sealingly engage a first orifice and a second valve member coupled to the valve stem and configured to sealingly engage a second orifice. The second valve member can include a coupler for coupling the second valve member to the valve stem and a seal configured to couple to the coupler and the valve stem. The second valve member can be configured for achieving proper spacing between the valve members for simultaneous contact with their respective orifices without the need for more costly and time consuming components or assembly methods.
