Proportional valves

Get smooth, accurate control of your pressure and flow applications with our range of proportional screw-in cartridge (SiCV) valves. When applied in combination with Eaton logic element valves and other SiCV in a custom manifold assembly, Eaton proportional valves create an efficient, reliable hydraulic system.
Proportional valves
FEATURES
Maximum flexibility and minimum space
PRESSURE RATING
Up to 350 bar (5,000 psi)
FLOW RATING
Up to 160 L/min (42 gal/min)

Choose your flow control

Choose from a wide range of proportional valves, including options such as:

  • Bi-directional or uni-directional
  • Poppet or spool
  • Normally closed or normally open
  • Relief or inverse relief
  • Pressure reducing
  • Nose-in, side-out or side-in, nose-out flow direction

Hardened and ground materials

All operating parts are made from hardened and ground steel, which provides maximum durability and leak protection.

Enhanced corrosion protection

Eaton cartridge valves and coils can be supplied with zinc plating, and aluminum manifolds can be anodized to improve corrosion resistance.

 

 

Pulse width modulation (PWM) control circuits recommended

Get the most accurate control using PWM-controlled hydraulic circuits and Eaton proportional valves.

Internally rectified coils

Eaton internally rectifies standard AC coils to supply them with DC current and avoid an "in-rush" current.
