FAQs
To verify compatibility, confirm port size is R1/4, the maximum inlet pressure is 6.3 bar, and the medium is compressed air. The 1002/BG008’s brass body and compact 21 mm dimensions support direct connections to standard pressure sources and vessels, enabling straightforward installation without substantial modification to existing plumbing.
Install the valve with secure mounting to the pressure vessel and ensure correct orientation to minimize ingress. The unit ships pre-set and tamper-resistant, reducing the likelihood of accidental adjustments. Use appropriate fittings and avoid non-approved pull rings; this preserves the set-point and maintains leak integrity across the installation.
Yes. The 1002/BG008 operates from -40 to 230 °C, making it suitable for a wide range of factory environments. For harsh conditions, verify compatible seals and consider the overall system exposure, condensate management, and potential chemical exposure to ensure long-term reliability.
The provided data does not specify certification marks. When selecting for regulated facilities, confirm with the supplier about CE, IP ratings, and SIL-related standards as required by your plant. Request formal certification documentation to ensure conformity with your regulatory and safety requirements prior to installation.
Relief valves like the 1002/BG008 help prevent costly downtime by limiting over-pressurization events and protecting downstream equipment. Its tamper-resistant design reduces service time by avoiding frequent recalibration, and its compact footprint lowers installation costs. Overall, expect improved uptime and lower risk of pressure-related failures in demanding production lines.
