WEBTEC VFD120-E Série Mode D'emploi page 3

Introduction
Aimed at mobile and industrial applications the VFD120-E can be used for controlling hydraulic motor and cylinder
speeds by applying voltage to the valve which in turn controls the flow rate.
Variable priority flow dividers split a single input (P) flow into a priority (REG) flow and an excess or by-pass (BP)
flow which can be returned directly to the oil reservoir or used to power a second system. This is possible due to the
valve's adaptive pressure compensation characteristics meaning both the priority and by-pass flows can be used to
drive separate circuits, even under varying loads. In many instances this dispenses with the need for another pump to
operate a second system.
The VFD120-E design has also been optimised to reduce energy wastage by minimising the pressure losses across the
valve, resulting in a significant reduction in running costs.
Webtec have been designing and manufacturing flow meters and hydraulics components for over 50 years. We operate
within a Quality Management System that complies with the requirements of BS EN ISO 9001 which is externally
audited and certificated each year. Beyond compliance to the standard, Webtec is committed to continually improving
in everything we do; with particular emphasis on understanding what matters to our customers and suppliers, and
designing our systems and work to meet their needs. We are always keen to hear from customer who may have special
requirements not covered by our standard ranges.
