QUICK GUIDE:  Which style air control valve does your lift need?

Semi-Hydraulic Single-Post Lifts

  • Requires a NON-locking air control valve
  • A semi-hydraulic single-post does NOT have an oil control valve

Full-Hydraulic Single-Post Lifts

  • Requires a LOCKING air control valve
  • A full-hydraulic single-post also has an oil control valve

Important note:  The locking/non-locking air control valve question only applies to single-post, in-ground lifts, whether the lift is full-hydraulic or semi-hydraulic.  All other style in-ground lifts including two-post side x sides and two-or more post ~ fore and aft lifts, are ALL full-hydraulic and use LOCKING air control valves.   If you need clarification on this please call me at (331) 442-9150 before you buy
