ENVIZION stainless steel fail open

The Biopharm industry relies on hygienic diaphragm valves for
demanding process applications due to their unique balance of
clean-ability, drain-ability and pressure/temperature capability.
For more than 40 years the technology of these valves has
changed very little. Advances in performance have been
nominal as the basic design concept has remained the same:
body, diaphragm, topworks, and four fasteners. This design
requires experienced personnel and stringent maintenance
practices to assure consistent, reliable valve performance. All
while the industry is forced to increase productivity, extend
preventative maintenance intervals, and reduce operating costs. ITT’s breakthrough technology, the EnviZion valve, sets a new standard for the future of hygienic diaphragm valves. The EnviZion valve is designed specifically to help customers install, operate, and maintain their valves more efficiently. This unique design provides a significant reduction in total cost of ownership while supporting the industries’ goals to increase productivity, improve reliability and enhance
clean-ability.
