Compact design: The 61B2/BN000 is a miniature pop-type pressure relief valve that fits directly onto pressure vessels, eliminating bulky interfaces and simplifying installation. Business impact: Reduced footprint means smaller enclosures, faster assembly, and lower shipping costs, while a simplified path to compliance reduces project risk. Application: Ideal for pneumatic circuits in automation panels, robotics end-effectors, and compact actuator banks where space is at a premium.\n\nTemperature resilience and material choice: With an operating range of -20 to 80 °C and a brass body, the valve maintains consistent performance in harsh factory environments and mobile equipment. Business impact: Enhanced durability translates to lower maintenance intervals and less unexpected downtime. Application: Suitable for globally distributed plants where environments vary from cold docks to warm machine rooms, while brass construction adds robustness against corrosion in standard compressed air service.\n\nFlow and inlet pressure: Maximum inlet pressure 4 bar and a flow rate of 4.92 dm3/sec ensure reliable relief for small to mid-size systems. Business impact: Prevents over-pressurization without sacrificing system responsiveness, supporting safe startup sequences. Application: Directly protects pressure vessels and downstream components in blow-off lines, tool feeds, and compact pneumatic circuits with R1/4 ports.\n\nProtection and maintenance: Pre-set and tamper-resistant relief valves guard against ingress to protect the preset setting and maintain consistent operation. Business impact: Reduces accidental adjustments and theft of settings, lowering service calls and calibration time. Application: OEM integrations and field installations benefit from plug-and-play reliability and compatibility with Norgren accessories and standard porting.\n\nIndustrial relevance and procurement: The 61B2/BN000 aligns with a broad range of valves and manifolds, enabling modular designs, interoperability with other Norgren products, and faster procurement cycles for OEMs upgrading panels to compact relief solutions.

FAQs
The 61B2/BN000 uses an R1/4 port size and is rated for a maximum inlet pressure of 4 bar, with a relief flow of about 4.92 dm3/sec. This combination provides rapid response to pressure spikes while protecting downstream equipment. The brass body offers durability for standard compressed air service in small to medium pneumatic circuits.
Yes. The valve features a brass body with a compact footprint that aligns with typical OEM panel designs and standard porting. Its R1/4 connections support direct installation, and it remains compatible with Norgren manifolds and accessories, helping streamline stocking and reducing integration risk in automated lines.
Install the valve with a direct R1/4 connection to the pressure vessel, ensuring clean media and operation within -20 to 80°C. Use the pre-set, tamper-resistant option to prevent unauthorized adjustments and protect against ingress. Confirm enclosure clearance for a 20×20×40 mm footprint and the 0.052 kg weight during panel layout.
Ideal for automation panels, conveyors, robotics actuators, and compact pneumatic lines. It provides over-pressurization protection at a 4 bar setpoint while allowing rapid venting to maintain safe startup and operation. The direct vessel connection and brass body support reliable performance in small to mid-size circuits in plant-wide automation.
Maintenance is minimized by the pre-set, tamper-resistant design and ingress protection features, reducing calibration needs and field service calls. The compact form factor lowers stock and lead times, while reliable operation minimizes downtime, delivering a faster return on investment through improved line availability and reduced repair costs.
