Hex stock, hard seat
6000 and 10,000 PSI

The GTH series are machined from hexagonal bar stock and supplied in 316 stainless steel and carbon steel with nickel zinc plate.

  • All bonnets are assembled with a locking pin to prevent accidental removal while in service
  • Teflon® packing can be adjusted to increase valve life
  • Stem packing below the threads prevents lubricant washout and ensures no process contamination
