Key Features

• Bellows Seal Zero-Leakage Protection
  Multi-layer metal bellows provide a hermetic stem seal, eliminating external leakage and ensuring safe handling of corrosive and hazardous media.

• Superior Corrosion Resistance
  Available in stainless steel and special alloy constructions to withstand aggressive chemical environments and extend service life.

• Designed for Hazardous Media
  Prevents fugitive emissions and ensures safe containment of toxic, flammable, or high-risk fluids.

• Ideal for High-Purity Applications
  Smooth internal structure facilitates cleaning and supports high-purity process requirements in fine chemical, pharmaceutical, and semiconductor industries.

• Double Sealing Safety
  Secondary packing behind the bellows provides additional protection and operational security.

• Reliable Long-Term Performance
  Durable internal components resist corrosion and wear, reducing maintenance frequency.

• Material Construction
  Standard EN-JL1040 (Cast Iron) models available for general applications.

• Operating Temperature Range
  -10°C to 120°C (14°F to 248°F) for cast iron models.

• Pressure Ratings

  • PN6 / Class 50

  • PN16 / Class 150

• Connection Options
  Available with Flanged and Screwed Socket end connections.

• Compact Size Range
  Sizes from 1/2” to 2” (DN 15–150) for small to medium industrial systems.

• Suitable Media
