摘要
A valve having a valve cap with a plurality of process conduits extending therethrough, each one of the plurality of process conduits ending in a process port at a valve cap interface. The valve also has a valve body defining a valve body interface facing the valve cap interface, a diaphragm positioned between the valve cap interface and the valve body interface, across the process ports, and a purge line provided through one of the valve cap and the valve body. The valve further comprises a sealing assembly located in the valve body. The sealing assembly is configured and positioned to block fluid leaked through the diaphragm such that the fluid leaked through the diaphragm is discharged via and exit of the purge line of the valve. A chromatographic system including the valve and a method of operation thereof are also provided.
