- Wellbore fluids do not come in contact with any threads, elastomer seals or O rings.

- The solid tungsten carbide cage and plug provides exceptional resistance in erosive conditions.

- The non-threaded seat sleeve eliminates thread washout and overcomes corrosion issues within the body and greatly simplifies its removal and replacement.

-The stainless steel micrometer orifice indicator is extremely accurate for onsite configuration of stem position and used in calibration and comparative readings for SCADA digital feedback and readouts.

-The enlarged cage reservoir and cage design reduces the possibility of body cavitation and limits vibration to reduce noise.
