Smaller, lower cost solenoid cartridge valves with improved performance
13 April 2017
Eaton has introduced its ESV9 series of proportional solenoid cartridge valves which help offer a more cost effective, general-purpose solution when compared to industrial-rated valves.
The ESV9 valves are also smaller, reducing the manifold size and cost, and allow increased flexibility during installation. The valves offer control with optimised linearity, operational efficiency and low hysteresis less than 7 percent. 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 ideal 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-energized 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 per minute and up to 250 bar.
“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”, says Andreas Kling, Product Marketing Manager Power & Controls Products EMEA at Eaton. "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.
Applications include construction machinery, agricultural, material handling as well as a broad range of general equipment.
