  • RPTFE – improved strength and better service reliability
  • Metal Seat – suitable for more demanding temperature and industrial conditions

Pressure & Temperature Range

Pressure Capability

Available in Class 150, 300, and 600 depending on application, size, and design requirement. Proper class selection is essential for safe operating reliability.

Temperature Suitability

Temperature capability depends on seat material and service media. PTFE and RPTFE are suitable for many industrial services, while metal seats are used where higher temperatures are involved.

Advantages

Easier Maintenance

Central body section can be serviced more easily without disturbing complete line configuration.

Strong Shut-Off Performance

Floating ball arrangement provides dependable isolation and industrial sealing performance.

Better Long-Term Serviceability

Suitable where maintenance access and periodic internal replacement are important.

Limitations

  • Usually higher cost compared to simpler 2 piece designs
  • More body joints than a 2 piece construction
  • Selection should be justified where maintenance advantage is actually needed
