Key Product Features:
  • Low Operating Torque: Features a unique plastic sliding cover on the wedge, which reduces friction against the body guides, ensuring smooth operation and low torque even after years of service.
  • Resilient Sealing: The fully encapsulated rubber disc provides a bubble-tight seal and compensates for minor imperfections in the pipe or debris, preventing leakage.
  • Compact Non-Rising Stem: The stem does not rise during operation, making this valve ideal for installation in pits or areas with limited vertical space.
  • Corrosion Resistance: The ductile iron body is typically coated with fusion-bonded epoxy (FBE) to prevent corrosion and ensure safe contact with potable water.
  • Versatile Application: Suitable for water supply networks, power plants, industrial settings, and pressure management systems.
