Product Description

Product Description

Description

CAN bus-control proportional directional spool valve is base on the load-sensing principle. It is proportional directional spool valves. Each directional
valve is integrated with proportional solenoid, spool position sensor and digital closed-loop controller, which ensures that the main spool valve
moves fast with high-precision position control ability. By presetting optimized dither signal and high-performance control algorithm, and the output
flow of the proportional directional spool valves is more accuracy, this help the operator getting excellent control accuracy when they controlling the
equipment. Therefore this valve is the best choice for closed-loop or high-precision control application.

 technical characteristics

Technical features
1. small dead zone, fast response, easy to achieve closed-loop control of cylinder position
2. Closed-loop control of multi-way valve spool position, with smaller hysteresis and higher repeatability of output flow
3. Simplified wiring, only 4 wires are needed for the whole set of Proportional directional spool valves, power line", CAN-Hand CAN-L bus signal lines
4. Each directional valve is equipped with a parallel double DEUTSCH connection socket, which can be connected to the host computer separately
5. Quick connection between valves via double plugs for easy maintenance and repair
6. plug terminal resistor (1200) can be installed in the first or last connection of the Proportional directional spool valve as required
7. with fault diagnosis function, easy to troubleshoot

Specification

 CAN bus proportional directional spool valves contains connection block, directional spool valves, end plate and electronic control module (digital
controller+ proportional solenoid). The 4 pins of the connection plug receive 12-30VDC power supply, when the 1,2 pins receive the command signal
in accordance with the CAN bus protocol format, the CAN bus interface will convert the signal into the command signal corresponding to the main
spool position, the main spool of the directional spool valves is equipped with a position sensor, which can detect the spool position feedback in
real time and convert it into a corresponding voltage signal to the digital signal processor, the error of the command signal and the actual position
signal is delivered to the current signal amplifier after the PID algorithm, and the amplifier outputs the PWM current signal with the dither signal to the
proportional solenoid ,then the pilot proportional valve open, and the pilot oil pushes the main spool to move, when the position of the main spool is
the same as the command signal, the spool stops moving until the command signal changes. So the Flow is proportional to the command value.
Note: Do not give the command signal to the proportional directional spool valves without oil supply, avoid electronics damage.
