Eaton Integrated Proportional Valves

Eaton Integrated proportional valves create an efficient, reliable hydraulic system when combined with logic element valves and screw- in cartridge valves in a custom manifold assembly. They provide maximum flexibility and smooth, accurate control.

Pressure ratings are up to 350 bar (5,000 psi), flow rating up to 160 litres/minute.

The range of Eaton Integrated proportional valves includes 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.

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

With maximum hysteresis of 7%, the ESV9 four-way, three-position proportional valve gives precise control in a variety of applications.

The ESVL9 five-way, three-position proportional valve features a patent-pending integrated load sense check valve. Integrating the check valve in the main cartridge results in a 21% manifold size reduction compared to external check valves available on traditional five-ported directional control valves.

Both valves feature optimized flow forces and jet as well as a dual-spring design, for stable, even flow control.
