  • Maximum pressure 210 bar.
  • Minimum pressure 4 bar.
  • Suitable for natural gas supply.

Hydraulic Cylinder

  • Made of carbon steel.
  • Fully welded for better pressure resistance.
  • Maximum pressure 210 bar.
  • Equipped with a manual hydraulic pump for the manual operation of the actuator, mounted directly on the actuator.
  • Manual pump connected to the hydraulic cylinder by means of stainless steel pipes and fittings.

Surface treatments

  • Actuator and carriage are phosphate-plated;
  • The entire external surface of the actuator is sandblasted and coated with epoxy powder, RAL3020 as per standard, another color on request.
