Key Features

• Bellows Seal Zero-Leakage Design
  Multi-layer stainless steel bellows provide a hermetic stem seal, completely eliminating external leakage and ensuring environmental safety.

• Double Sealing Protection
  Graphite packing installed behind the bellows offers secondary sealing protection, maintaining safety even if the bellows is damaged.

• Ideal for High-Temperature Service
  Designed for steam systems, thermal oil circuits, power plants, and industrial heating applications.

• Enhanced Operational Safety
  Prevents fugitive emissions and reduces the risk of hazardous media leakage in high-temperature environments.

• Hard-Faced Seat Construction
  Wear-resistant seating surfaces improve resistance to erosion and corrosion under high-pressure and high-temperature conditions.

• Reliable Long-Term Performance
  Engineered for extended service life with reduced maintenance frequency in demanding industrial applications.

• Material Construction
  Available in EN-JL1040 (Cast Iron) for standard applications.

• Temperature Range
  Operating temperature from -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.

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

• Suitable Media
  Designed for water and water systems with cold protection requirements.

• Low Emission Compliance
  Bellows sealing minimizes atmospheric emissions, supporting environmental compliance standards.
