Compact, High Purity, Low Flow, Low Pressure, Back Pressure, Jorlon Diaphragm with lifetime warranty
The JSBLFLP is a fully drainable compact back pressure regulator
designed and built specifically for hygienic, ASME BPE low flow
and low pressure gas and liquid applications.
- It's been designed specifically to eliminate all threaded connections
and contaminant traps below the diaphragm.
- It is completely drainable (an industry first in compact hygienic
regulator design), and compatible with CIP and SIP
practices. See drainability guideline on page 6.
- The simple trim design facilitates quick trim change out and
cleaning without valve removal or complete disassembly.
- Fully drainable with no threaded connections, or contaminant
traps below the diaphragm
- In-line removable trim significantly reduces maintenance
- Barstock construction guarantees material integrity and
- Minimized internal volume
- Proprietary Jorlon diaphragm material provides exceptionally
long life and CIP/SIP capability, and FDA and USP Class VI compliance and is warrantied for life.
