| MODEL F PLUNGER TYPE FLOAT VALVE |
Model F DPFV provides positive and instantaneous shut off against high and low pressure, assuring continuous control of fluid during drilling, including H2S applications. It is the most economical choice for normal drilling operations and is available in all sizes. Made of alloy steel body and dimensionally identical to the standard Float Valve, it has interchangeable trim and is recommended for use with downhole mud motors. |
| MODEL FA DRILL PIPE FLOAT VALVE |
Model FA DPFV offers all the standard features of Model F with an added port allowing a fluid path through the valve’s center. It is recommended for monitoring the bit head when differential pressure is required. Available in all sizes. |
| MODEL G FLAPPER TYPE FULL OPEN VALVE |
Good for use with highly abrasive fluids, with a flapper design to open quickly and fully, providing a completely unrestricted bore through the valve. When circulation stops, the flapper closes instantly to prevent cuttings from entering the drill string and plugging the bit. It opens when the first joint is raised out of the hole, ensuring the first joints drain and are not pulled wet. All flappers for Model G are made of low alloy steel 8620 with QPQ treatment to resist wear and erosion, providing unrestricted flow of drilling fluid during circulation. |
