Features

Safe & Leak-free

  • Specially designed for use with highly aggressive media.

  • Sealing system proven and perfected over decades.

  • Optimal performance with technically advanced components.

Ecological & Economical

  • Extended service life due to the spherical construction of the sealing surfaces of the disc and liner.

  • The rounded and polished disc minimizes torque and enables the use of smaller, more economical actuators.

  • Intricately shaped support rings extend the service life of the valve.

Extra Features

  • Modified PTFE significantly improves durability in contact with chlorine, hydrogen fluoride, high temperatures, and other heavy-duty applications.

  • Guaranteed compatibility with all common actuator systems thanks to various shaft mounting options.

Unique

  • Adaptable for different industries thanks to the modular design.
  • Individual serial numbers guarantee full traceability of all pressurized and load-bearing parts.
  • Continuously developed in collaboration with our customers.
