The CVS series stainless steel one-way valve has a fixed opening pressure and multiple opening pressures to choose from. The valve body is made of high-quality SS316L material, and the inner surface can be selected for EP electrolytic polishing, high cleanliness treatment, degreasing and precision cleaning. Each valve undergoes a separate helium mass spectrometry leak test before leaving the factory.
