IMI Norgren V07-200-NNLG Valves & Flow Control - 20 bar Max Inlet
Part Number: V07-200-NNLG
Quick Summary
V07 Series pressure relief valve protects compressed air systems from over-pressurisation in industrial automation lines. When system pressure spikes occur, users face leaks, increased wear, and unexpected downtime; this valve mitigates that risk with a compact form and knob-adjusted control. Common certifications to verify for this class include CE compliance, SIL safety alignment, and appropriate IP protection; verify your regional regulatory requirements. Designed for quick integration with G1/4 ports and Rc1/8 gauge ports, it delivers reliable protection in tight control panels and remote locations, aligning with modern factory automation needs and helping maintain consistent downstream pressures for sensitive tooling.

FAQs
Yes. The V07-200-NNLG is designed for 07 Series compatibility and can be mounted with the 18-025-003 neck mounting bracket. This integration reduces install time, aligns with existing Norgren components, and ensures robust alignment for reliable operation in compact assemblies.
The outlet pressure is adjustable from 0.3 to 8 bar (4 to 116 psi) using the knob on the bonnet. For accurate settings, depressurize the line before adjustment, verify the downstream pressure with a gauge, and perform incremental changes while monitoring the system response.
This valve protects pneumatic lines and tools in automation and machining environments, especially where space is limited. With G1/4 ports and a Rc1/8 gauge port, it suits compact control panels, tool chests, and remote manifolds, providing controlled relief to maintain steady downstream pressures.
The data provided does not list specific CE or SIL certifications. Verify compliance with your regional standards. For EU projects, CE marking is commonly required, while SIL considerations depend on system-level safety architecture and adherence to applicable standards in your control scheme.
Maintenance can be supported with the V07-KIT service kit, which streamlines part replacement and seal renewal. Following a planned service schedule helps maintain sealing integrity (Nitrile elastomer) and outlet accuracy, reducing unscheduled downtime and extending service life in demanding air systems.
