New solenoid cartridge valve offers more flow for less power

A low-power, low-pressure-drop solenoid valve solution for compact equipment has recently been launched by Danfoss Power Solutions.

The global supplier of mobile and industrial hydraulics and electric powertrain systems, says its SLP13 two-way two-position poppet-type solenoid valve features patent-pending technology that significantly reduces power consumption while increasing flow rating, which can help original equipment manufacturers (OEMs) meet efficiency targets and reduce manifold size and cost.

The cartridge valve reduces power consumption from 29 W to less than 10 W, helping to extend run time in battery-operated vehicles. Danfoss explains that by reducing power consumption, the stabilised temperature of the valve’s new coil has been reduced by nearly 50%, which helps prevent coil burnout and enables longer service life.

The SLP13 valve features a lower pressure drop than previous generation solenoid valves, aimed at improving fuel efficiency and reducing emissions. The valve is designed to allow approximately 1.8 times more flow in the same cavity compared to conventional products. It also allows for larger valves to be replaced with smaller ones, resulting in a more compact, lightweight, and lower-cost system.

“Machinery trends such as the increasing use of onboard electronic controls and the growth of compact and electrified equipment demand efficient, low-power valves and hydraulic integrated circuit solutions. Representing a significant advancement in flow rating and power consumption, our new SLP13 valve is well positioned to help OEMs capitalize on these trends,” said Danfoss Power Solutions global product manager: integrated circuit solutions Abby Bauer.

Available in size 10 with a nominal flow rate of 79 l a minute and pressure rating of up to 350 bar, the SLP13 valve is said to be suited for a variety of materials handling, construction and agriculture machinery applications.
