Power management company Eaton, whose US headquarters are located in Ohio, recently announced the company’s ESV9 series of proportional solenoid cartridge valves. The new valves aim to provide excellent operational efficiency and a broad ramp rate for greater resolution and ease of use.
The size 10 ESV9 is a four-way, three-position screw-in cartridge and is available with either a type closed or float spool configuration. The E-spool type solenoid valve has all the ports closed in the de-energized position. This configuration is can be used 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-energized 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 in the de-energized condition.
