Smaller and lower cost cartridges improve performance

The valves offer control with optimised linearity, operational efficiency and low hysteresis less than 7%. Broader ramp changes also allow greater resolution.

The size 10 ESV9 is a 4-way 3-position screw-in cartridge and is available with either a type E or F spool configuration. The E-spool type solenoid valve has all the ports closed in the de-energised position.

This valve is suitable for moderate flow applications where an actuator needs to be proportionally controlled in both directions and stopped in any position. The F spool in the de-energised condition ports 2 and 4 are open to tank with the inlet port 3 blocked. This allows the service ports to decay to tank pressure in the de-energised condition. The size 10 ESV9 valve has a rating of up to 22l/min and up to 250bar.

Andreas Kling, Product Marketing Manager Power and Controls Products EMEA at Eaton commented: “The introduction of the ESV9 series will help provide significant up-front cost savings to our customers, complementing Eaton’s Cetop 3 industrial-rated, high-flow KDG4-V3 series. The smaller package size of the ESV9 series also reduces the manifold size and cost.”

As an option, the valves are available with a manual override and additionally be fitted with or without the IP69K compatible ‘L Series’ Large ToughCoils. 12 or 24V DC coil voltages, with or without a diode, can be selected, along with a number of housing materials (steel or aluminium) and port sizes.
