ITT Pure-Flo Sanitary Diaphragm Valves

The ITT Pure-Flo Familty of Sanitary Diaphragm Valves

The weir type diaphragm is the only truly fully draining, straight through, sanitary process valve on the market today. We carry the ITT Pure-Flo line of sanitary diaphragm valves for the biopharmaceutical industry. ITT Pure-Flo is the sanitary diaphragm valve industry leader offering a comprehensive line of 2-way forged body and multiport machined from block valves, both manual and actuated. ITT sanitary diaphragm valves offer manual bonnets in a broad choice of materials and several actuator/automation packages.

We carry an extensive inventory of ITT Pure-Flo sanitary diaphragm valves in sizes 1/4"-4". We also maintain a large inventory of ITT diaphragm valve spare parts and ITT valve replacement diaphragms.

Look at the New ITT Pure-Flo EnviZion Hygienic Diaphragm Valve
The ITT Pure-Flo Envizion Valve

ITT's new EnviZion valve is a breakthrough technology in hygienic valves for the Life Sciences Industry. The EnviZion valve is designed to help users install, operate and maintain their valves in a more efficient, hygienic and cost effective manner. It's unique design the biggest technological breakthrough we have seen in weir type diaphragm technology since the advent of the block body valve.

The EnviZion valve utilizes a breakthrough mount and turn design that allows for quick and easy valve disassembly. Features and benefits include:

  • Tool-less maintenance: No tools are required for valve installation and diaphragm replacement, simplifying the maintenance process.


  • Fasteners eliminated: No more handling loose parts or accessing fasteners in tight spots. Exposed threads are eliminated, making the valve more hygienic.

  • Time saving: The average industry time required to change a diaphragm is 23 minutes. The Envizion valve diaphragm can be changed in 3 minutes.

  • No re-torquing: The seal is maintained over varying operating conditions, eliminating the need to adjust fasteners after thermal cycling
  • Bonnet Removal and Valve Maintenance Made Easy
    Bonnet Removal is a Simple 3 Step Process without Tools

    ITT Pure-Flo 4-Way Divert Sanitary Diaphragm Block Valve

    ITT Pure-Flo has a long history of developing innovative solutions to satisfy the sanitary diaphragm valve needs of the Biopharm industry. Until recently, many piping challenges were solved by welding standard valve bodies into complex webs of piping. Now using powerful 3D modeling software, a wide variety of solutions are available. 3D modeling allows the ITT Pure-Flo Solutions Group to develop sanitary block body diaphragm valve designs that meet the most demanding requirements. They offer the following benefits:

  • Shorter deadlegs resulting in reduced hold-up volume
  • Reduced CIP cycle times
  • Fewer expensive field welds resulting in lower installation time and costs
  • Smaller process piping footprint
  • Standard ITT Pure-Flo Standard Block Configurations
