SYSTEM FOR TESTING VALVES
First Claim
1. A chamber assembly for testing a valve, the chamber assembly comprising:
- a proximal chamber portion that defines a proximal interior space;
a distal chamber portion that defines a distal interior space, the distal interior space including a gas space, wherein when a liquid is inserted into the proximal and distal chambers there is an interface between the liquid and a gas in the gas space; and
a valve holder that is disposed adjacent to the proximal interior space and the distal interior space, the valve holder configured to receive the valve in a bore of the valve holder, wherein a shortest distance between a center of the valve when in the bore and the interface is at least about 45 mm.

Abstract
A chamber assembly for testing a valve includes a proximal chamber portion that defines a proximal interior space, and a distal chamber portion that defines a distal interior space. The distal interior space includes a gas space. When a liquid is inserted into the proximal and distal chambers there is an interface between the liquid and a gas in the gas space. A valve holder is disposed adjacent to the proximal interior space and the distal interior space. The valve holder is configured to receive the valve in a bore of the valve holder. A shortest distance between a center of the valve when in the bore and the interface is at least about 45 mm.

9. A system for testing a valve, the system comprising:
a chamber assembly comprising; a proximal chamber portion that defines a proximal interior space; a distal chamber portion that defines a distal interior space, the distal interior space including a gas space, wherein when a liquid is inserted into the proximal and distal chambers there is an interface between the liquid and a gas in the gas space; and a valve holder that is disposed adjacent to the proximal interior space and the distal interior space, the valve holder configured to receive the valve in a bore of the valve holder, wherein an area of the interface As in cm with the liquid at rest is set so that an agitated liquid depth Da is no greater than a distance from the interface to a top edge of the valve, wherein the agitated liquid depth is a distance that agitated liquid with bubbles reaches below the interface in cm during testing of a valve. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system for testing a valve, the system comprising:
a chamber assembly comprising; a proximal chamber portion that defines a proximal interior space; a distal chamber portion that defines a distal interior space, the distal interior space including a gas space, wherein when a liquid is inserted into the proximal and distal chambers there is an interface between the liquid and a gas in the gas space; one or more baffles which are located in the distal interior space at least partially on a first side of the interface and at least partially on a second side of the interface with the liquid at rest, the one or more baffles reducing reflection of waves in the liquid off sides of the distal chamber portion; and a valve holder that is disposed between the proximal interior space and the distal interior space, the valve holder configured to receive the valve in a bore of the valve holder. - View Dependent Claims (18, 19, 20, 21)
