SSWN-32/V

Wheel Operated Stainless Steel Diaphragm Gland Seal Cylinder Valves for Speciality Gases

SSWN-32/V is wheel operated design using a two-piece spindle separated by non-perforated diaphragms. The five diaphragms in series act as gland packing and prevent leakage around the valve spindle when the valve is in open condition. The replacement of elastomeric seals (as in O-ring seal design valves) with metal diaphragms gives the valve superior leak integrity to the atmosphere. There are no threads or lubricants in the gas stream to generate particles or contaminate the gas. The design prevents diaphragm inversion, and all this makes the design ideal for use with applications involving toxic, high purity, rare, pyrophoric, and even corrosive gases.
