IMI Norgren 61B2/BS000 Mini Pop Valve - 4 bar

Part Number: 61B2/BS000
Manufacturer
Norgren
Part number
61B2/BS000

Quick Summary

Mini Pop Valve provides compact pressure relief for compressed air systems in small equipment. When over-pressurization occurs, downtime, component damage, and costly repairs threaten productivity. Note: Certifications such as CE, SIL, and IP ratings should be verified in the official datasheet. This IMI Norgren valve uses a brass body with a direct R1/4 connection and a pre-set, tamper-resistant relief mechanism. For OEMs and maintenance teams, it delivers reliable protection with a compact footprint, straightforward installation, and predictable performance in automated systems.

FAQs

The 61B2/BS000 uses an R1/4 port with a maximum inlet pressure of 4 bar, suitable for compact compressed air systems and small pneumatic circuits.
Install the valve via a direct connection to the pressure vessel using the R1/4 port. Ensure mounting is secure and that the brass body is clean and free of debris to maintain a tamper-resistant, leak-free seal.
With a flow rate of 4.92 dm3/sec, the valve provides moderate relief capacity suitable for typical small- to mid-range pneumatic circuits while protecting components from over-pressure.
The valve is pre-set and tamper-resistant, protecting against unintended adjustments and ingress. Regular inspection of the valve and surrounding connections is recommended as part of standard preventative maintenance.
