Product Description

● Utilizing mature and reliable PVE electro-proportional control technology, the system simplifies installation and setup while incorporating load-sensing technology to enhance efficiency and reduce power consumption.

● Flow is unaffected by changes in the main load, ensuring more precise operation—SIL 2-certified digital actuator (PVED-CX)

● Flexible system design

● The PVG valve group is designed to provide customers with exceptional flexibility in system design. Its modular architecture offers nearly limitless configuration options, allowing you to easily adapt to future changes. Additionally, the load-sensing technology helps minimize wear on other system components, significantly extending the machine’s lifespan. Our high-quality valve groups are built to be robust and durable, delivering outstanding control performance day after day.

● Advanced electric drives

● We offer a comprehensive range of electric drives, spanning from simple ON/OFF control to advanced CAN-bus communication-based control. Our cutting-edge PVED-CC and PVED-CX digital drives are specifically designed for compatibility with the J1939/ISOBUS protocols and CANopen systems. Additionally, the PVED-CX is SIL 2 certified (meeting the requirements of IEC 61508 for SIL2), ensuring compliance with the European Machinery Directive 2006/42/EC—and helping you streamline both system and vehicle certification processes while significantly reducing associated time and costs.
