The Type F plunger type valve offers positive and instant shut-off. In normal drilling operations the model F offers economy and durability.

The piston type stops flow-back when making connections and keeps cuttings out of the drill string.

The flapper valve style allows full flow through valve, designed for highly abrasive fluids.

When ordering, please specify:

  • Type F or G
  • Float Valve Size or connection size
