Norgren V07-200-NNKG Pressure Relief Valve - G1/4 ports
Part Number: V07-200-NNKG
Quick Summary
V07-200-NNKG pressure relief valve protects compressed air systems from over-pressurisation in industrial automation lines. In many installations, sudden pressure spikes stress actuators, cause leaks, and waste energy when relief is mismatched. These devices align with common safety standards, including CE conformity and rugged IP-rated considerations, and are SIL-ready when integrated with safety circuits. By combining a compact form with a knob-adjustable outlet and reliable materials, this valve delivers precise relief control while simplifying maintenance. For engineering teams, this translates to less downtime, extended equipment life, and predictable process performance across varied factory environments.

FAQs
The V07-200-NNKG uses G1/4 porting with an Rc1/8 gauge port for monitoring. It supports 07 Series neck mounting via the 18-025-003 mounting bracket and is compatible with the V07 series manifold configurations. This simplifies retrofits and new installations alike, reducing the need for additional adapters and ensuring consistent performance in compact layouts.
Outlet pressure is adjustable from 0.3 to 7 bar (4 to 100 psi), allowing precise relief to protect downstream actuators. The valve is rated for a maximum inlet pressure of 7 bar, which defines the upper bound for safe operation in standard compressed air systems and helps prevent over-pressurisation under peak conditions.
Yes. With a compact zinc body, acetal bonnet, and nitrile elastomer seals, the V07-200-NNKG is designed for continuous operation in typical factory environments. Its knob-adjusted control and robust materials support reliable relief across frequent cycling, minimizing downtime and ensuring steady process pressures in conveyors, pick-and-place cells, and other automated equipment.
The V07-200-NNKG is designed to align with common industry safety standards and EU conformity considerations. While specific certifications such as CE, IP ratings, or SIL readiness depend on system integration and regional requirements, it is widely used in compliant industrial environments when installed with appropriate enclosures and controls. Always verify certifications within your project scope and with the system integrator.
The V07-KIT service kit simplifies routine maintenance by providing genuine components for the knot adjuster, seals, and related wear parts. Regular, kit-based maintenance reduces unexpected failures, extends valve life, and lowers total cost of ownership by minimizing unscheduled downtime and preserving consistent relief performance across shift cycles.
