ベローズシールゲートバルブ
ベローズシールゲートバルブは、一次シールをグランドパッキンではなくボンネットとステム間の溶接金属ベローズとします。ベローズはステムのストロークに伴って伸縮するため、ステムの動きによって漏れ経路が開くことはありません。ベローズとパッキンの二重シール構造を採り、組立品はヘリウムリーク試験でゼロ漏れを確認するため、有毒・可燃性流体や真空でのフュージティブエミッション用途に対応します。基準となる鋳造シリーズはNPS 2"～30"（DN50～DN1650）、ASME Class 150～1500（PN16～PN260）、炭素鋼・ステンレス・合金鋼・低温鋼・デュプレックス・Ni基合金ボディ、RF・突合せ溶接・RTJ端接続、手動・空圧・電動・油圧操作に対応し、小口径鍛造シリーズはNPS 3/8～2、Class 150～2500です。ベローズは316Ti、Ni-Mo合金、Ni-Cr合金、Ni-Cu合金の2プライ以上をハイドロフォーミングし、非回転ステム+バックシート、二次シールとしてAPI 624パッキンを装備します。定格と同様に運用制限が重要です。全開/全閉のみ（スロットリング不可）、有限のサイクル寿命、遅いハンドホイール操作、ベローズ室への摩耗粉混入を避けるための清浄流体。

| End connection types | SW – ASME B16.11, NPT – ASME B1.20.1, BW – ASME B16.25, FLANGED – ASME B16.5, FLANGED – BS EN 1092, COMPACT FLANGE – NORSOK L-005, HUB – According to Customer Request |
| Operation / closure mode | Manual, Pneumatic, Electric, Hydraulic |
| Design standards | Design per API 602, ASME B16.34 and MSS SP-117, inspection and testing per API 598 and MSS SP-117, fugitive-emission compliance per API 624, ISO 15848 and TA Luft. |
| Design standards | ASME B16.34, ASME B31.3, ISO 15761, API 602, API 600, MSS SP-117 |
| bellows leak test | Every bellow assembly is helium leak-tested to assure zero leakage; each valve is tested per API 598. |
| secondary stem seals | Stem backseat plus API 624 stem packing act as secondary stem seals behind the bellow. |
| stem design | Non-rotating stems prevent torsion of the bellow during stroke. |
| bellows materials | 316Ti, nickel-molybdenum alloy, nickel-chromium alloy, nickel-copper alloy |
| bellows construction | Bellows are hydroformed with a minimum of two layers (plies). |
| packing standard | High-quality packing per API 622 for low-emission performance compliant with API 624; seal-welded bellows isolate the packing from process media. |
| small bore segment | Forged small-bore bellow-sealed segment: NPS 3/8 to 2 (DN10-DN50), ASME Class 150 to 2500. |
| dual seal redundancy | Bellows and packing form a dual sealing structure: the bellows is the primary stem seal and the packing backs it up, so a bellows failure does not become an immediate leak path. |
| gate duty limit | Bellow-seal gate valves are for full opening and closing only; adjustment and throttling are not permitted. |
| bellows maintenance | Bellows are critical components and require regular inspection for leaks, damage, or deterioration; replace promptly when found. |
| duty environment | Particularly suitable for harsh service involving toxic, flammable or explosive media, or high temperature and pressure conditions. |
| cycle life limit | Avoid exceeding the designed number of opening and closing cycles to prolong the bellows lifespan. |
| operation care | Operate the handwheel or actuator slowly to avoid damaging the bellows through excessive force or speed. |
| medium cleanliness | Ensure pipeline cleanliness so impurities do not enter the valve cavity and affect sealing performance. |
| bellows rupture response | On bellows rupture: cease operation immediately and close the upstream and downstream isolation valves to prevent media leakage. |

注文と書類
書類
お問い合わせの際に必要な書類セットをお知らせください——この型番仕様の典型的な項目（材質証明書、記載の検査規格に基づく試験報告書、寸法図）は、見積時に確認のうえ供給されます。
お見積り
見積可能なお問い合わせには次の事項をご記入ください：呼び径と圧力レーティング、ボディ・シート材質の希望、接続方式、操作方式、温度を含む使用流体。このページの典型値はベンチマーク参考範囲です。拘束力のある値は見積時に確定します。
サンプルと供給
供給条件、発注数量、納期は注文ごとに協議します——お問い合わせの際に納入国と希望スケジュールをお知らせください。
保管と輸送
バルブはシート・シールを紫外線、オゾン、変形から保護して保管し、据付まで端面保護カバーを取り付けたままにしてください。エラストマーまたは PTFE シートの仕様では、屋外での長期保管を避けてください——シート材料は直射日光と凍結条件で最も劣化が早くなります。
