Hydraulic cylinders for operating valves and gates.

Hydraulic Cylinders are designed and manufactured to operate valves and gates, constructed from seamless drawn steel pipe with an internal mirror finish.

The piston rod usually installed by INHISA is chrome-plated 431 stainless steel, machined for optimum sliding and durability. Hardened and tempered stainless steel piston rods can also be installed for highly corrosive environments.


Hydraulic Cylinders are made up of the following main elements:

  • Sleeve
  • Piston rod
  • Seals and packing
  • Connecting elements (flanges, trunnions, joints, etc.)


INHISA designs Hydraulic Cylinders according to the following principles:

  • Ensuring maximum durability and reducing maintenance
  • Corrosion protection
  • Position transducers can be fitted
  • Optimised for hydro-mechanical equipment
