Gas-liquid booster cylinder
HZ series split working cylinder
Working pressure: ≤6bar

Pressure: 2-2000 kN

Power stroke: 5-52mm

Total stroke: 100/200/250mm

Pneumatic-hydraulic drive combines the advantages of compressed air and hydraulic systems, combining the high-speed movement of the cylinder with the high strength of the hydraulic system. A gas-hydraulic drive is a specially designed cylinder that requires a supercharger to drive low-pressure oil to achieve rapid forward stroke. After reaching the designated position, the supercharger provides high-pressure oil to complete the work.
