Ceodeux Puretec Unveils the D304 to the Tied Diaphragm Valve Series
Ceodeux introduces new standard flow cylinder valves for use with ultra high purity and corrosive gases.
The innovative double-seal of the D304 combines a soft seat made of PCTFE (also available in Vespel and PVDF) with a mechanical stainless-steel stop; preventing over-torquing of the valve. The double-seat combination significantly reduces the gas permeation rate and extrusion of the soft seat disc, which in turn increases the lifetime of each valve. The D304 also allows for metal-metal sealing in the event that a burn out of the soft seat should occur.
As always Ceodeux incorporates safety and functionality into all of its products, the D304 is no different. Each valve is manufactured and tested to CGA V-9 and ISO 10297 standards, and is available with pressure relief devices in accordance with CGA S-1.1.
Since 1922, Ceodeux has continually strived to provide the industry with the most sought after and beneficial products and features. Years of experience and ingenuity have gone into the development of this product and the same trusted valve technology that is in all Ceodeux valves has been applied to the innovative D304.
