10 Two-Stage High-Performance Proportional Directional Valves With On-board Electronics

Feb. 1, 2008
Diversified industrial manufacturer Eaton Corporation has added the KBFDG5V-10 two-stage proportional directional valve with on-board electronics and main stage spool feedback to its line of Vickers™ products. Designed for high-flow applications requiring accurate speed profiling and position control, the new valves are rated for flows up to 700 liters per minute and pressures up to 350 bar, and feature best-in-class IP 65 and IP 67 environmental protection ratings.“These valves are designed to provide superior control and performance in applications including plastic and rubber machinery, metal forming, die casting machines, primary metal production equipment, power generation, and similar uses,” said Wayne Wang, product manager - industrial valves for Eaton’s Hydraulics Operations. “With their standard ISO mounting interfaces and industry standard seven-pin electrical connectors, these valves are truly plug-and-play.”The new KBFDG5V-10 valves use a spring-centered spool and dual-solenoid pilot valve to provide fail-safe performance, and provide main spool feedback to the on-board electronics, which feature an integral amplifier pre-loaded with factory-preset adjustments for consistent flow gain and excellent valve-to-valve reproducibility. Other standard features include:•    4-20ma or +/-10V command input option•    “Fail safe” feature•    New digital on-board electronics with available ramp adjustment•    Optional external valve enable feature•    Full CE electromagnetic capability to EN50081-2 & EN50082-2•    Robust die-cast housing for the on-board electronics•    Vibration and shock tested
