ダブルオフセットバタフライバルブ
ダブルオフセットバタフライバルブはシャフトを中心線とシート面の両方から偏心させ、開弁時ほぼ直ちにディスクがシートから離れるため、同心型に比べ摺動摩耗が大幅に減ります。範囲はDN50～DN600、PN10～PN63 / Class 150～1500、ウェーファー端接続、ボディはダクタイル鋳鉄・WCB・SS304/SS316、ディスクはアルミブロンズまで対応、ステムはSS410系、ボディシートは13Cr～コバルトクロム硬化合金溶覆（ステンレス+グラファイトシール上）、操作はギアまたはアクチュエータ。設計はAPI 609 / DIN 2559 / EN 593、面間はASME B16.5 / DIN3202 F4 / EN558-1、試験はAPI 598。選定は偏心シート設計に対するクラス、温度に対するシート組合せ、相手フランジに対するウェーファー長がポイントです。

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。
