Core features:
• True bidirectional sealing, capable of withstanding pressure differences from both sides
• High temperature and high pressure resistance, suitable for steam, heat transfer oil, and high-temperature gases
• Wear-resistant and erosion-resistant, suitable for media containing particles and dust
• Easy opening and closing, with a service life far exceeding that of ordinary hard seals
• Zero leakage is achievable
Sealing Surface Material
• H: Cr13 series stainless steel, general purpose
• Y: Hard alloy, more wear-resistant and high-temperature resistant
• W: Body stainless steel, corrosion resistant
Common Sealing Rings:
• 304, 316, duplex stainless steel, hard alloy, etc.
