On behalf of ITT, Holland Applied Technologies is pleased to announce the Envizion Advantage actuator option that is now available for the EnviZion hygienic valve product family. The Advantage actuator is a diaphragm driven, compact, lightweight actuator designed to meet the stringent space constraints of the
The EnviZion Advantage Actuator
Bioprocessing and Pharmaceutical Industries. The unit is designed as an on/off pneumatic actuator available with three modes of closure.
The EnviZion Advantage pneumatic actuator combines the well-known and ultra-reliable Advantage actuator with the breakthrough EnviZion thermal compensation system to provide the ultimate in overall valve reliability. The diaphragm driven EnviZion Advantage actuator allows the EnviZion valve to be utilized in applications requiring precise control. The EnviZion Advantage actuator also allows for more flexible conversion of operating modes, change of spring sets, and maintenance of the actuator.
The Advantage actuator platform has been utilized for more than 25 years in the Biopharmaceutical industry. The EnviZion Advantage is offered as follows:
- Valve Sizes: .75” – 2” (DN 20 – 50)
- Operating Modes: Fail Closed (60# and 90# spring sets), Fail Open, Double Acting
- Actuator Material: Glass Reinforced Polyethersulfone (PES)
- Bonnet Material: Stainless Steel
- Corrosion Resistance: Resistant to common industry wash downs.
- Thermal compensation system
- Safety lock-pin
- Visual position indication
- Weep hole
- 360 degree airport rotation
Let us take this opportunity to revisit the EnviZion sanitary valve and what makes it special. It begins with the top works; the bonnet for all EnviZion valves are mounted to the valve body with a simple twist and secured with a few turns of a locking cover. The rest of the “tools” needed for assembly are all within the bonnet itself. This simple assembly process also engages the most innovative feature of the EnviZion valve platform: a thermal compensation system that ensures a 360 degree active seal at all times – even following SIP.
Just how effective is the thermal compensation system that was engineered into this valve? The EnviZion hygienic diaphragm valve passed the testing required by ASME BPE 2014 Edition Appendix J – Standard Process Test Conditions (SPTC) For Seal Performance Evaluation.
The ASME BPE Standard was established in 1997 for the design of equipment for the production of biopharmaceuticals. The SG Sealing Components subcommittee of ASME published Appendix J as a set of standard process test conditions for seal performance including diaphragm valve diaphragms.
The ASME BPE 2014 Edition Appendix J test provided validation of the integrity and liability of the EnviZion valve’s live thermal cycle compensation system. The valve received the maximum cycle rating, classified as a Level 500 seal corresponding to the number of SIP exposure/cool-down cycles, from ASME after it completed the test at three times the required test pressure.
What does this mean for the end user? It means we’re going to eliminate a tremendous amount of downtime and further reduce the possibility of losing a batch of valuable product due to a valve leak because the Teflon diaphragm creeped. By minimizing downtime, we maximize uptime, effectively increasing the capacity of the system. These two features- decreased chance of leakage and increased productivity- make the valves extremely economic when viewed from a total cost of ownership perspective.
The EnviZion valve platform was developed with one overarching goal – to reduce the customer’s total cost of ownership. Costs associated with installation, validation, operation, and maintenance are significantly reduced with the EnviZion valve. Backed by extensive in-house testing, independent third party ASME BPE Appendix J testing, and EHEDG certification, the EnviZion valve is setting a new standard for the performance of hygienic diaphragm valves.
