EnviZion

ITT’s breakthrough technology, the Pure-Flo® 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.

Overview	Mount and turn design allows the removal of the bonnet in 3 quick and easy steps No tools required for valve installation and diaphragm replacement Integrated thermal compensation system eliminates the effects of thermal cycling Replacing diaphragms is now up to 90% faster with the EnviZion valve Adjustable travel stop for overtightened protection
Material	316L and WN1.4435 stainless steel
Options	Autoclavable Actuation packages available Enhanced surface finishes and electropolishing ATEX certified Seal bonnet option Comprehensive range of feedback switch and control options

BioviZion

The BioviZion™ incorporates all of the performance and innovative features of the EnviZion valve but into a much smaller package developed specifically to address low flow bioprocess applications. The patented diaphragm stud design shared with the EnviZion makes replacement diaphragm installation a fraction of the time of a standard bolted valve. The BioviZion valve is available in 1/4” – 1/2” sizes with clamp or weld end connections.

Zero static ‘T’ valves

Zero Static “T” Point of Use (POU) valves are some of the most critical valves utilised in the Biopharmaceutical industry today. Point of Use valves allow process fluids to be transferred, sampled, drained or diverted with minimal impact on critical systems such as Water for Injection (WFI) and Purified Water (PW).

Overview	Comprehensive range of orientations and size combinations Completely drainable design Body machined from block 3D models and drawings available
Material	316L and WN1.4435 stainless steel
Options	Manual and actuated options Enhanced surface finishes and electropolishing Integral sample option (ZSBBS) ATEX certified Comprehensive range of feedback switch and control options
Literature	Pure-Flo catalogue Zero static dual inline Zero static downstream purge Zero static inverted with drain Zero static back to back sample Zero static block body tee Zero static block body with back outlet Zero static block body U-bend Zero static block body with vertical run With upstream sample and downstream purge

Divert valves

Multiport Divert valves allow process medium to be diverted or mixed. Divert valves are instrumental in achieving cost effective and efficient piping design, coupled with reduced product “hold up” by minimising dead legs.

Overview	Sizes 1/2″ – 6″ 2 way to 6 way as standard options Choice of horizontal or vertical options 3D models and drawings available
Material	316L and WN1.4435 stainless steel
Options	Manual and actuated options Enhanced surface finishes and electropolishing Multiple port orientation options ATEX certified Comprehensive range of feedback switch and control options

Fabricated assemblies

Custom assemblies can be fabricated to meet customer process requirements using a combination of standard 2-way valves and block valve combinations where necessary. The Sterile Access and GMP valve combination is typically used for sampling, purging, diverting and drain applications.

Overview	Choice of size combinations, orientation, porting and custom design Minimised dead legs due to factory fabrication Reduced installation time 3D models and drawings provided for approval process
Material	316L and WN1.4435 stainless steel
Options	Manual and actuated combinations 0.25 – 6″ (DN8 – ISO) Enhanced surface finishes and electropolishing ATEX certified ASME BPE/DIN/ISO end connections butt weld and clamp Comprehensive range of feedback switch and control options

Block body valves

The Integrated block body program was developed to meet the ever increasing requirement of compact valve designs to meet customer space and envelop constraints. The weir type diaphragm design enabled design engineers to start machining multiple valve weirs into a single block of stainless steel. The advantages are numerous.
