Flexible proportional solenoid cartridge valves Eaton

Eaton’s ESV9 series of proportional solenoid cartridge valves are designed to provide superior control with optimized linearity. Utilizing an optimized get with dual spring design, the ESV9 spool is more highly controlled than single spring designs, with less than 7% hysteresis and higher maximum flow. A broad ramp rate also ensures a greater resolution and ease of use.

The size 10 of ESV9 is a four-way, three-position screw-in cartridge, available with either a type closed or float spool configuration. The E-spool type solenoid valve has all ports closed in de-energised position, ideal for moderate flow applications where an actuator needs to be proportionally controlled in both directions and stopped in any position. The float or motor spool in the de-energised condition features ports two and four open to tank with the inlet port three blocked. This allows the service ports to decay to tank pressure. The ESV9 has a rating of up to 22 liters-per-minute and up to 250 bar, matching the technical requirements of most applications.

The valves are also available with manual override and can additionally be fitted with IP69K compatible L series Large ToughCoils. The solenoid valves are available in 12 volt or 24 V direct current coil voltages, with or without a diode, along with a number of housing materials (steel of aluminum) and port sizes. In mobile construction, agriculture and material handling applications, the valve can be used in place of Eaton’s industrial-rated, high-flow KDG4-V3 valve series, providing a more cost-effective, general-purpose solution. The ESV9 valves are also smaller, reducing the manifold size and cost, and allow increased flexibility during installation.
