控制s for proportional valves are used in hydraulics when it is necessary to precisely and reliably control large capacities and forces. In the shipping sector the controls ensure that winches and cranes can raise and lower their loads at a consistent speed. Industrial applications include controlling moulding presses, and in a wind turbines with a hydraulic pitch system, the valve controls adjust the position of the rotor blades to suit the prevailing wind conditions.
最多可以通过Bachmann电子的单个PVA200模块单独控制八个液压阀。它们也适合连接大量更大的阀门，因为它们可以使用高达2.5安培的电流。
即使在全速下快速配置
Whether on board ship or in an industrial plant, it must be possible to exchange valves while they are running, quickly and regardless of manufacturer or type. Thanks to the latest configuration tools in Bachmann’s own engineering software SolutionCentre and in the web configurator, the valve control’s parameter settings are incredibly straightforward and do not require any other special tools or specialist knowledge. The technician on site simply selects the preconfigured replacement valve in the software program and the control does the rest.

高准确率
The current-regulated activation of the PVA200 module prevents any temperature differences from influencing the valve position. The low target/actual value difference under five milliamps also ensures a high repeat accuracy. The current is fully configurable, whereby the maximum flow rate can be defined dependent on the process. There are up to 20 sampling points available for correcting the valve characteristic, which enables very precise linearization with the least possible effort.
Hydraulics: Controls with web configuration make swapping proportional valves incredibly easy
• Reliable use for valves subjected even to the greatest mechanical forces • One single control for up to eight proportional valves • Valves of every make and type can easily be configured online and on site
