- Parameters
Spool moves directly to precisely defined position to meet requirements for precision control
Pilot pressure not required, ensuring no affects from external influences such as pressure and temperature fluctuations, viscosity or contamination
Can be used in all climate zones, including those as warm as +100 °C and as cold as -40 °C
With the precise matching of the spool and the sleeve, the performance is same as a servo proportional valve.
Provides ease of operation by enabling synchronous operation of up to six actuators in the same mode with post compensators
Targeted at applications where machines are designed for flow rate of 120 l/min and operating pressure of 250 bar
Operated by brushless electric stepper motor with integrated electronics, which in turn is controlled via CAN bus
Integrated electronic drive module with fault diagnosis and CAN bus communication function
Without sensors CAN actuator eliminates previously typical overshoot, no tendency to oscillate
Required flow rates can be set more precisely, and opening points can be approached with linear resolution of 7 µm
Capable of spool reaching high travel speeds (80 mm/s at 12V or 100 mm/s at 24V)
Intelligent actuator ensures reproducible positioning of control spool, without hysteresis
Neutral position is determined at every start to ensure safety
Getting the best out of hydraulics, CAN technology and stepper-motor control, pinpoint accuracy in all climates
SANT Hydraulics combines the Smart series directional valve, which has proven itself in numerous applications and is constantly being enhanced, with a CAN actuator. Now the valve is operated by a brushless, electric stepper motor with integrated electronics, which in turn is controlled via the CAN bus.
The new mechatronic system offers a broad range of applications around the globe, regardless of climate zones. The strengths of the system are demonstrated in both extreme cold and extreme heat. The applications for the system are therefore many and varied: from snow groomers, through tractors and self-propelled harvesters up to municipal vehicles. No pilot pressure is required for operation, making the Smart valve resistant to external influences such as pressure- and temperature-fluctuations, viscosity changes and contamination.
