Product description
Inline style, manual or air loaded, pressure reducing valves for low flow clean compressed air and gas point of use applications in the biopharmaceutical, pharmaceutical, food & beverage and consumer health & beauty industries.Applications
- Bioreactor/fermenter: sparge gas, purge/blanket/motive force gas for gas regulation
- Separation: purge/blanket/motive force gas for process vessels
- Purification: purge/blanket/motive force gas for process vessels
- Formulation: purge/blanket/motive force gas for process vessels
- Lyophilization: purge gas regulation
- Clean utility: CCG (clean compressed gas) pressure control for post SIP drying of small vessels, tubing, filters, etc.
- F & B consumer H & B process purge/blanket/motive force gas regulation

Features and Benefits
- Stable outlet pressure setpoint regulation as low as 1 psig (68 mB)
- Top entry design facilitates in-line cleaning and maintenance
- Barstock construction guarantees material integrity and quality surface finish
- Four Cv’s from 0.01 to 0.2 guarantee an application fit
- Large, proprietary Jorlon diaphragm provides exceptionally long life and sensitivity to minimal pressure changes
- Low lock-up with EPDM seat
Note: These valves may be used on non-cavitating liquid or clean steam applications. However, they are not drainable. Steriflow Engineering must review application before acceptance
