- Immediate flow shutdown if downstream equipment fails
- Protection of downstream equipment from overpressure conditions
- Allowance of test string to be hung from the elevator
- Enable rotation of the string without rotating the flowhead
- Double metal-to-metal seals for reliability in harsh environments
- Remote activation
- Automated flow valve closing if control pressure is lost
- A kill-line connection for pressure testing, injection, or killing the well
- A swab valve in which tools can be introduced and ran into
- Protection frame on main block for manual and hydraulic valves to improve durability
- Four point liftable skid with forklift pockets to allow handling and movement
- Swivel between master valve and main valve block to allow subsurface equipment to be rotated with respect to main flowhead block
