The IP8081/1P8181 intelligent electrical valve positioner is an intelligent two-wire field instrument based on microprocessor technology. It is a high-performance electrical valve positioner that can effectively overcome frictional forces and unbalanced forces on the valve core, improve the response speed of the regulating valve, and enable rapid and accurate positioning; It has functions such as changing control type, setting split range control, setting closed function, changing valve stroke distance, adjusting packing friction coefficient, setting valve type, and 4-20mA valve position feedback. It is used in conjunction with traditional mechanical-electrical valve positioners, making the installation and debugging of valve positioners more convenient, with lower maintenance costs and higher control accuracy.
Product Overview
High positioning accuracy, up to 0.5% F.S.
Easy to operate; generally only one click is needed to complete the setting.
It has an explosion-proof function, safe and reliable performance.
Automatic tuning, automatic diagnosis.
Good seismic performance. Long-term use will not cause zero drift problems like mechanical locators.
Low power consumption, low-cost operation.
Adopting a two-wire 4-20mA standard signal.
