On-off solenoids and on-off valves
Thomas on-off solenoids are also used in differential and reduction transmissions, where they activate things such as the clutch to turn off individual drive axles in all-wheel systems. This leads to further reduction in the fuel consumption and emissions of the vehicles. Our on-off solenoids are renowned for their dynamic switching speeds and enormous energy and power efficiency.
On-off valves along with proportional valves are also used in the hydraulic steering of dual-clutch and automatic transmission systems, where they serve to activate the clutch and on-off functions.
