セラミックダイバーターバルブ

強酸に強い (塩酸, HF), アルカリ, 有機溶剤, and high-salt media; service life 5–10× that of stainless steel valves.

Ceramic sealing surface hardness ≥ HRA 90; matching precision ±0.005 mm; leakage rate Class VI (ANSI/FCI 70-2).

Density only 1/3 of metal; reduces driving power consumption; suitable for pneumatic/electric quick-response systems.

All-ceramic flow path with zero metal ion leaching; compliant with FDA & GMP.

Sizes DN5–DN200; 2-way / 3-way / multi-port designs available.

化学薬品: Diverting corrosive media (塩酸, H₂SO₄, HF); reactor feed control.

半導体: Ultra-pure chemicals, フォトレジスト, エッチング液, CMP slurry, UPW.

医薬品: Sterile filling, bioreactor media switching.

水処理: Wastewater chemical dosing, backwash systems.

エネルギー:H₂ circulation for fuel cells, lithium battery electrolyte dosing.

静水圧プレス + precision grinding; sealing surface Ra ≤ 0.2 μm; matched CTE to avoid thermal cracking.

100,000-cycle life test; helium leak test <1×10⁻⁹ mbar·L/s; chemical compatibility & particle testing (SEMI F57 Class 0).

標準 2 週; 軍の慣習 4～8週間.

Sizing software, インストール, commissioning, maintenance.
