BPAV™

バックリングピンAPIバルブ-API526標準配管設計


性能

  • サイズ：1x 1½インチ ～ 8 x 10インチ (25mm x 40mm ～ 200mm x 250mm)
  • 背圧の影響を受けないので背圧が変化したり継続してかかる場合に適しています
  • パイプラインを開く必要がなく、外部から即時リセットが可能
  • 短いダウンタイム(即時インライン外部リセット)
  • 危険なサービスを回避(オペレーターのプロセス側からの暴露を制限)
  • 大流量にも対応 - オリフィスなしの設計で気相の場合0.8、液相の場合は0.686の高Kd
  • 設定圧力比に対する高い作動圧力、最小で 95%
  • ASME"UD"スタンプ対応、section XIII
  • 欧州圧力機器指令「CE」マーク

    Saf-T-Pin™ Buckling Pin Cartridge

    The BPAV can be provided with buckling pin cartridges that are installed like an electrical fuse. The Saf-T-Pin buckling pin cartridge allows a “quick-change” option of buckling pins with a simple push-in/pull-out design for installation within the enclosure. Each Saf-T-Pin cartridge contains a calibrated buckling pin that is perfectly mounted for optimum performance.

    Replacement Buckling Pins

    Stainless steel pins with tags containing pressure and traceability information including the serial number of the BPAV device.
