How Pure-Flo's EnviZion Valve Lowers Cost and Improves Production

Selection Guide The Pure-Flo® valve has earned a reputation for innovation, quality and performance. Providing products from standard forged valves to the most innovative block technology, each and every Pure-Flo® valve is engineered to the highest standards.

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 cleanability.


Advantages of The ITT Pure-Flo EnviZion Hygienic Diaphragm Valve

PROBLEM WITH TODAY'S VALVES: DIAPHRAGM REPLACEMENT Today's hygienic diaphragm valves use four (4) fasteners to connect the valve, body, diaphragm and top works. Valve disassembly process is rigorous, and care must be taken when removing and replacing fasteners. Often diaphragm replacement is complicated by valves that are installed in hard to reach locations with limited access. Maintenance professionals in the biopharma industry have confirmed that the average time to replace the diaphragm in today's valve design, is approximately twenty three minutes.

After changing the diaphragm, the fasteners must be evenly tightened to the manufacturer specifications, to ensure a proper seal. These fasteners commonly require a re-torque after this system has reached full operating pressure and temperature. Diaphragm replacement is a critical procedure, and if proper installation can result in process fluid leaking, system downtime, and increased maintenance costs.

NACE Standards White Paper: Measuring the Pressure of Sour Gas and Crude

White paper courtesy of Ashcroft.
Every mechanically activated pressure instrument relies on an elastic element to bend in response to a pressurized medium. Most often, the element is a metallic “C” shaped or coiled Bourdon tube that attempts to straighten under pressure. Specifiers need to be especially careful that the chemical  composition of the excitation medium does not react unfavorably with the instrument’s wetted materials. Measuring the pressure of compressed air or water seldom results in an incompatibility. However, when oil and gas first come out of the ground, the story can be quite different. Both hydrogen sulfide (H2S) and carbon dioxide (CO2, when combined with water forms carbonic acid) can exist as unwanted components. Raw petroleum fluids infused with hydrogen sulfide are known as “sour gas” or “sour crude”, and can attack containment materials, causing stress corrosion cracking. This can lead to a breach in the vessel and allow gas or oil to escape into the surrou…
