Screw-In Cartridge (SIC) Valves for Mobile & Industrial Use

Directional Valves Screw-In Cartridge (SIC) – spool version

The ARGO-HYTOS screw-in cartridge program offers a wide function range for mobile and industrial hydraulics. Typical functions are flow direction control and pressure control in the hydraulic circuit. The most common applications are, for example, agricultural machines, construction equipment, municipal services vehicles, machine tools and wind power plants, among others. The ARGO-HYTOS range of valves represents in its design the best performance achieved thanks to a design optimized with the help of modern simulation methods and high-quality manufacturing processes.´

Screw-in cartridge spool and poppet Version

These valves are designed to control the flow direction. There are two sizes available, based on ISO/TR 17209 standard for threaded cavities 3/4-16 UNF and 7/8-14 UNF. The operating pressure is up to 350 bar. Two performance product families are available in order to choose the best-fit solution.
To compensate misalignments of the cavity production, all cartridge spool valves are equipped with the unique feature of a tumbling nose which prevents blocking of the spool in the cavity, thus ensuring a long life and robustness of the assembly. Poppet versions are available up to 150 l/min and 420 or 350 bar pressure, applicable for all ports.
Precision machined parts secure leak-free closing (less than 3 drops/minute). For spool and poppet cartridges, two performance product families are available in order to choose the best-fit solution.

  • High performance for 350 bar or 420 bar circuits
  • Lightline for 250 bar circuits

Design features:
ARGO-HYTOS offers in its design increased technical specification for all standard valves

  • Reliability of design with lifetime of 10 Mio cycles at rated pressure - also valid for the seals
  • High operating pressure and flow power limits in each size coupled with low pressure drops
  • Extended surface protection 520 h according to DIN 9227 Standards
  • Extreme resistance to high or low oil and ambient temperatures
  • Optimized design for best ratio between pressure drop, transmitted hydraulic power and leakage

New poppet valve size 12, 150 l/min, 350 bar
In the year 2018, ARGO-HYTOS will introduce a new family of poppet valves, normally open and normally closed for high flows up to 150 l/min. These valves are intended for use in mobile and stationary applications to achieve low pressure drops and high transmitted power. The new valve SD3E-C2 offers:

  • Leak-free closing - less than 3 drops/minute
  • Reliability of design with a lifetime of 10 Mio cycles at rated pressure - also valid for the seals
  • High operating pressure up to 350 bar coupled with low pressure drops
  • Extended surface protection 520 h according to DIN 9227 standards
  • Extreme resistance to high or low oil and ambient temperatures
