High pressure valve with multi-piece stator assembly

A biocompatible valve with a multi-piece stator assembly, comprising:

• a shell having a first side and a second side and having a plurality of threaded ports on the first side, each of the ports extending from the first side to the second side of said shell, and wherein the shell comprises metal, a polymeric material, a ceramic material, or a combination thereof;
• and
• a stator insert having a substantially planar first side and a substantially planar second side, wherein the first side and the second side are substantially parallel and Wherein the first side of said stator insert comprises a plurality of second ports each corresponding to one of the plurality of threaded ports of said shell and wherein each of the plurality of second ports comprises a fiat bottom sealing surface from which a fluid channel extends to the second side of said stator insert, wherein each of the plurality of threaded ports has a first diameter Dl and each of the plurality of the second ports has a second diameter D2, wherein D2 is greater than or equal to D1, wherein said stator insert comprises a biocompatible material, and wherein the shell and the insert are adapted to allow tubing to extend into each of the plurality of threaded ports and sealingly engage with the first side of the insert.

A multi-piece stator assembly for a valve, the assembly comprising;

• a shell having a first side and a second side and having a plurality of threaded ports on the first side of the shell and extending therefrom to the second side of the shell, wherein each of the plurality of threaded ports is adapted to removably receive tubing therein;
• and
• an insert having a first side and a second side, wherein the first side and the second side are substantially parallel, wherein the first side of the insert comprises a plurality of second ports, each corresponding to one of the plurality of threaded ports, wherein each of the plurality of second ports is adapted to removably receive tubing therein and comprises a flat bottom sealing surface from which a fluid channel extends to the second side of the insert, wherein the shell and the insert are adapted to allow tubing to extend through each of the plurality of threaded ports and sealingly engage with the flat bottom sealing surface of the corresponding one of the second ports.
