JSR Series - Gas Pressure Regulator
Brand: Steriflow ValveJSR is the first high purity gas pressure regulator designed and built specifically for hygienic, ASME BPE gas applications.
Traditionally, manufacturers adapted their industrial gas regulators for use in biopharm by simply changing the construction materials and surface finish.
Not so with the JSR.
It's been designed specifically to eliminate the exposed threaded connections and permanent contaminant traps below the diaphragm.
And, it features an in-line removable trim set to facilitate quick trim change out and cleaning without valve removal or disassembly.
The durable valve body and metal trim components are machined from ASTMA479 316L SST barstock and finished to ASME BPE SF5 (20Ra micro-inch, electropolished) standard.
The valve is outfitted with the rugged Jorlon diaphragm and Teflon, PEEK, or EPDM seats and seals that are all FDA approved, USP Class VI compliant materials.
These materials of construction enable JSR to withstand the rigors of SIP and CIP processes if required. And, the new EPDM seat reduces lockup to less than 2.5 psig.
Features- No exposed threaded connections below diaphragm
- In-line removable seat and trim facilitate cleaning and maintenance
- Barstock construction guarantees material integrity and surface finish
- High flow rate coupled with high rangeability reduces need for reduced trim sizes
- Minimized internal volume
- Proprietary Jorlon diaphragm material provides exceptionally long life and CIP/SIP capability
- Soft seat material for ANSI Class VI shutoff
- New EPDM seat for low lockup and tight shutoff on no flow or deadhead blanketing applications
