Norgren 1002/BR008 Poppet Relief Valve tamper-resistant
Part Number: 1002/BR008
Quick Summary
The 1002 Series poppet relief valve protects compressed air systems from over-pressurization in industrial lines. Without reliable relief, pressure spikes can damage equipment, cause downtime, and drive maintenance costs higher. While official certifications aren’t listed here, the device employs a pre-set, tamper-resistant relief design with a robust brass body for demanding environments. This combination supports safer, more reliable automation pipelines and aligns with common pneumatics standards, while the compact form simplifies installation and reduces total cost of ownership.

FAQs
To install, depressurize the line, ensure compatible R1/4 fittings, apply appropriate thread sealant suitable for brass, then tighten to manufacturer torque recommendations. Connect directly to the pressure vessel or panel, verify a leak-free seal, and perform a controlled pressure test. The unit is designed for quick integration in standard pneumatic layouts.
Key specs include a maximum inlet pressure of 10 bar, operating temperature range from -40 to 230 °C, and a brass-bodied construction for durability. Medium is compressed air, and the port size is R1/4. It is a pre-set, tamper-resistant relief device intended to protect downstream equipment in automation lines.
Yes, within the 10 bar inlet limit and with a pre-set relief mechanism, it provides rapid relief without the need for frequent adjustments. Its compact brass body supports consistent performance under typical industrial cycling, reducing dwell time after relief events and minimizing downtime in automated processes.
The provided data does not list specific certifications like SIL, CE, or IP. For definitive certification details, consult the datasheet (R W en 5_3_750_1002) or contact the supplier directly. In practice, verify CE and relevant IP/SIL requirements for your region and application through your compliance team.
The tamper-resistant, pre-set relief design reduces the risk of unauthorized adjustments and lowers maintenance interventions. This translates to less unplanned downtime and a more predictable maintenance plan. In OEM environments, the valve’s direct-connection design also minimizes install time and warranty costs by simplifying integration and reducing leak paths.
