Product description
The JSRULP is a pressure regulating valve ideal for low flow, very
low pressure precision regulation of clean compressed air and gas used
in pharmaceutical and bio-pharmaceutical R & D, Pilot and Production
facilities.
Applications
It is designed specifically for use on traditional stainless steel and single use disposable applications including:
- Small sterile vessels
- Gas overlay (blanketing)
- SUD bag integrity testing/inflation - Incubators - Time/pres filling machine product hold vessels
