Suzhou BONRAY-BJT type multi-port valve electric actuator

The multi-port valve special intelligent electric actuator adopts bidirectional positioning, which can rotate forward and backward, and the channel selection adopts the principle of selection, with high positioning accuracy; the number of channels can be set, and the control mode is flexible (local control, remote switch control, remote bus control). The valve position on site is displayed by a high-resolution LCD screen, and a full display is adopted. The parameter setting uses menu operation, which is free from opening the cover for debugging and supports multiple languages such as Chinese, English, and Russian. Valve position detection uses an absolute position encoder, which does not produce mechanical wear between the transmission shaft and the sensor, high selection accuracy, good repeatability, wide temperature range, and is hardly affected by factors such as environment, temperature, magnetic field, and voltage fluctuation. It has a variety of protection functions, such as torque overload protection, automatic phase sequence adjustment, instantaneous reverse protection, power phase loss protection, valve jam protection, and electrical isolation protection
