A release malfunction during low-temperature testing was confirmed for release device model HPR-510, resulting in cancellation of the type approval for the affected vessel valves and the designation of the affected release devices for recall and replacement. HPR-400\/500 units shipped during the unfiled period had performance confirmed and may continue in use. Impact on installed products is currently unknown; however, a full recall and replacement will be implemented.

Under supervision of the Safety Center, samples of vessel valves fitted with release devices from the unfiled period were collected and tested. As a result, we confirmed that vessel valves equipped with release device model HPR-510 exhibited insufficient gas release during low-temperature testing. Consequently, the type approval for the affected vessel valves has been cancelled, and the affected release devices are subject to recall and replacement.\n\n### Response and Impact\nWe will recall and replace all release devices shipped during the unfiled period. At present, the issue has not occurred in installed products, and we judge that continued use is possible provided operators observe precautions during manual operation until recall and replacement are completed. We will prioritize recall and replacement for installations in low-temperature environments and issue advisories. Performance confirmation was completed for HPR-400 and HPR-500 units shipped during the unfiled period, so installed units of those models may continue to be used.","jir_financial_highlights":"Scope of impact: Unknown (Unknown)\nUnits shipped (affected release devices): 4,001 units (Unknown)","jir_category":"","jir_hashtags":"#FenwalControlsOfJapan, #Disclosure, #VesselValveReleaseDevice, #RecallReplacement","jir_key_figures":"Affected vessel valve: Type approval cancelled for vessel valve NFCV-1, Approval No. Yo-092\nAffected release device: Model HPR-510, Units shipped 4,001 units\nUnfiled period: HPR-400 January 1999\u2013April 2011, HPR-500 July 2008\u2013February 2010, HPR-510 February 2011\u2013September 2014","jir_meta_title":"Fenwal Controls of Japan, Ltd. \u2014 Notice of Cancellation of Type Approval and Recall\/Replacement of Gas Extinguishing Equipment\uff5cOctober 2026","jir_meta_description":"Fenwal Controls of Japan, Ltd. announces cancellation of type approval for vessel valves and recall\/replacement of release devices.
