The CVS series stainless steel check valve features a fixed cracking pressure with multiple pressure options available. The valve body is made of high-quality SS316L material, and the internal surface can be electropolished (EP) for high cleanliness. Each valve undergoes degreasing, precision cleaning, and individual helium mass spectrometry leak testing before leaving the factory.
