The valve drive motor is an electric actuator used in combination with valves and dampers. Its control methods include: ①Built-in feedback potentiometer type with nominal 135Ω for proportional control in combination with DDC controllers such as WY7211; ②Nominal 135Ω impedance input type for proportional control in combination with proportional action electrical regulators such as T9065 and T991; ③4-20mA DC input type for proportional control in combination with DDC controllers such as WY7211 and R20/21; ④ON/OFF and floating type for floating control in combination with DDC controllers such as WY7207. When combined with control valves, use Q455 valve connectors; when combined with dampers, use Q605 damper connectors for assembly. It has a variety of control input signal types. The actuator has low power consumption and long service life. The installation of auxiliary switches is simple. It can drive valves and dampers of various sizes through valve connectors.

Current pressure (I/P) transducer is a device that converts an electrical signal to an pneumatic signal. It is suitable for harsh environments and is waterproof, dustproof and anti-corrosion.

JX5121 Shaft Vibration Transducer is a simple and low-cost way to monitor rotating machinery shaft vibration directly with DCS, PLC interface. It can truly protect this type of equipment by monitoring the shaft vibration of main and auxiliary equipment such as steam turbine, compressor, fan and pump group. It has accurate measurement, stable and reliable performance, and strong anti-interference performance.
