摘要: The present invention is a sample valve for use in conjunction with gas chromatograph. design provides both the inertness and low permeability performance of diaphragm, an elastomeric material to apply adequate sealing pressure diaphragm seal mating surface center plate valve. This allows active be well polished without previous concern maintaining critical flatness surfaces machined parts.
