Abstract
A manifold body includes at least first and second valve body segments each comprising an upper perimeter wall portion defining a valve cavity and a lower base portion defining one or more flow ports, a unified leak test port, a first branch leak test passage extending from the unified leak test port to an outer peripheral portion of the valve cavity of the first valve body segment, radially outward of an outer seal surface in the valve cavity, and a second branch leak test passage extending from the unified leak test port to an outer peripheral portion of the valve cavity of the second valve body segment, radially outward of an outer seal surface in the valve cavity.
Claims19
A manifold body comprising:
- at least first and second valve body segments each comprising an upper perimeter wall portion defining a valve cavity and a lower base portion defining one or more flow ports;
- a unified leak test port;
- a first branch leak test passage extending from the unified leak test port to an outer peripheral portion of the valve cavity of the first valve body segment, radially outward of an outer seal surface in the valve cavity;
- and
- a second branch leak test passage extending from the unified leak test port to an outer peripheral portion of the valve cavity of the second valve body segment, radially outward of an outer seal surface in the valve cavity.
A valve body comprising:
- an upper perimeter wall portion defining a valve cavity and a lower base portion defining one or more flow ports;
- and
- a leak test passage formed in the upper perimeter wall portion of the valve body, with a first portion of the leak test passage extending axially through the upper perimeter wall portion to a leak test port exposed on an end surface of the upper perimeter wall portion, and a second portion of the leak test passage extending laterally or radially through a lower end of the upper perimeter wall portion to the valve cavity to intersect with an outer peripheral portion of the valve cavity, radially outward of an outer seal surface in the valve cavity.
