摘要： The present invention relates to valve plugs for reducing erosion of the valve plug head and/or seat. More specifically, this invention comprises a valve plug incorporating a choke transfer trim that reduces the time of exposure of the plug head and/or seat to high velocity and high pressure drop at the interface of the plug head and seat when the valve is in the closed position. The choke transfer trim transfers the flow control area of the valve away from the plug head/seat interface to a location downstream, thereby reducing erosion at the interface between the valve plug head and/or seat that is typically used for fluid throttling and shut off.

摘要： Micro check valves having a free-floating member for controlling flow of fluid in microfluidic and biomedical applications and methods of fabrication. A micro check valve includes a valve seat, a valve cap that contacts the valve seat and an untethered floating member that can move between the valve seat and the valve cap. Certain micro check valves have zero cracking pressure and no reverse leakage. Certain other valves may be configured to permit flow of fluid within a pressure range. The floating member can be solid or define an orifice, and the valve seat can have one or two levels. Valves can be configured to allow fluid to flow when the floating member is pushed by fluid against the valve cap or against the valve seat. The valve seat may be silicon or another material that is compatible with micromachining processes, and the valve cap and the floating member may be a polymer such as Parylene.

The valve head includes a continuous partition defining a fluid barrier between a sealing side and an external side of the valve head. Each of the first and second retention legs extend from a leg base positioned at the sealing side of the valve head to a distal end of the retention leg. Each of the first and second retention legs include a plug catch configured to interfere with an inside diameter of a fluid flow orifice or a pressure relief spring. The respective distal ends of the retention legs are spaced apart from one another, and the anti-tip fin extends from the sealing side of the valve head in a direction of the respective distal ends of the retention legs.
