Product description
Fully automated or hybrid back (inlet) pressure reducing valve for purified water, clean utilities and media in the biopharmaceutical, pharmaceutical, food & beverage and consumer health & beauty industries.
Applications
- WFI distribution loop: return loop pressure maintenance upstream of spray ball
- Media/buffer prep., upstream process
- input back pressure control for mixing buffer, media
- pressure maintenance and relief to sterile containment - Separation input and output control: for perfusion TFF, for Trans-membrane Pressure (TMP) control
- Pump head pressure maintenance or pressure bypass
- Agitator or pump seal water pressure maintenance
- F & B consumer H & B process inputs outputs, purified water and clean utilities

Wetted Material
- ASME SA479 316L (UNS 31603) is standard. EN 10272:2000 GR 1.4435, AL-6XN®, Hastelloy C-22 and others are optional
Surface Finish
- ASME BPE SF5, 20Ra (0,5µm) electropolish is standard, 8Ra (0,2µm) optional
Diaphragm Materials
- Jorlon FDA, USP Class VI, 316L, EPDM/Nylon (FDA only)
Soft Seat Option
- Jorlon, PEEK (all materials FDA, USP Class VI)
Features and Benefits
- Lifetime warranty of Jorlon diaphragm
- Low offset (creep)
- Modulates open during over pressure events allowing volume excess to be drained to sterile containment
- New integral gauge ports optional
- Removing spring force during Rinse/CIP/Rinse cycle allows valve to fully open with minimal line pressure
- No guiding surfaces in the fluid – minimizes particulate generation
- 100% 316L barstock body and trim
