Hengli offers HVSP proportional valves with integrated, intelligent electronics providing full integration into the bus network of mobile machinery with IP68 protection.
The internal closed-loop position design of the HVSP valve achieves spool position accuracy levels nearing the performance of a servovalve. This is accomplished by continuously comparing the set- point of a remote-control device (potentiometer, joystick, machine controller) with the feed-back signal generated by a high-precision Hall-effect position transducer.
Additional features of the HVSP with CAN-Bus control:
- Up to 10 sections
- High peak pressure rating: 350/420 bar (5040/6048 psi)
- Individual load independent flow control via section pressure compensators
- Low hysteresis
- Manual override
- Flow: Inlet maximum 150 lpm (39.6 gpm) (with valve compensators)
