Patent ID: 8235067

Claim:
An encapsulated valve system for pressurized fluids comprising: a first metal housing portion having a first facing surface, the first facing surface comprising a plurality of branch pathways formed as a recess within the first facing surface, wherein one of the plurality of branch pathways comprises a first aperture, the first metal housing portion further comprising one or more first half flange fittings; a second metal housing portion having a second facing surface, the second facing surface comprising a plurality of branch pathways formed as a recess within the second facing surface, wherein one of the plurality of branch pathways comprises a second aperture, the second metal housing portion further comprising one or more corresponding second half flange fittings configured to mate with the first half flange fittings; a disposable conduit comprising unreinforced polymer configured to be interposed between the first and second housing portions and disposed within the recess of the first facing surface and the recess of the second facing surface, the disposable conduit configured to carry a pressurized fluid therein; and a first automatically-controlled pinch valve actuator mounted on the first housing portion, a second automatically-controlled pinch valve actuator mounted on the second housing portion, wherein the first automatically-controlled pinch valve actuator is disposed on the first metal housing portion and oriented generally perpendicular to the first facing surface and comprises a pinching element configured to pass through the first aperture and wherein the second automatically-controlled pinch valve actuator is disposed on the second metal housing portion and oriented generally perpendicular to the second facing surface and comprises a pinching element configured to pass through the second aperture, the first and second automatically-controlled pinch valve actuators configured to pinch and close the disposable conduit at selective, different branch pathways.
