(Fisher) DVC2000 intelligent electric valve positioner details Fisher (Fisher) DVC2000 Series digital valve controller uses a simple, compact and easy to install. Instrument setup is via a push button and liquid crystal display (LCD) interface to carry out. The LCD interface supports multiple languages, including German, French, Italian, Spanish, Chinese, Japanese and English. DVC2000 Series digital valve controller uses a two-stage positioner design. Preamp provides high static gain for small changes of the input signal (0.125% or less) to produce a response. PA put enough air to the actuator, the equipment to achieve optimum dynamic performance at minimum air consumption at steady state. High performance non-contact position feedback system to avoid direct contact between the valve stem with the locator. So there will be wear and tear of parts, so that the action lifetime maximum. No connecting rod and coupling reduces the number of parts of the complexity of the installation and installation. Since the feedback components remain on the actuator stem, so locator replacement and maintenance is greatly simplified. Ordering Information (order information) 1.
