At31 series of motor-driven actuator system is used for all operation in need of 0-90℃ rotation, which can work with butterfly valve to adjust flow of gas or air, or work with linear valve, using three-point-type control signal. There are 2-cam and 4-cam types, of which the 2-cam type is default. Please inform if you need the 4-cam type. One of the 2 cams is used to adjust the smallest angle and the other to the largest open angle. The other 2 cams provide 2 groups of 0-90℃ adjustment. Working with output relay, when it runs to a certain position, it can provide 2 groups of switching value outputs for choice. There are 220V and 24Vpower-type for continuous control signal (AT..E)and two-point-type control signal (AT..R), of which the 220VAC is default. Please inform if you need 24V-type when making an order.

The connecting pendulum rod of the standard configuration accompanying the product before leaving the factory is used to connect the gas butterfly valve Please inform us when you don't need it, otherwise it is not easy to take it away.

Core features

High precision: repeated positioning accuracy is usually up to ± 0.5%, to ensure the combustion efficiency.

Rapid response: to adapt to frequently regulated needs (e. g. load changes).

High temperature resistance: Some models can withstand the high temperature environment (such as the actuators near the furnace body).

Self-diagnosis function: modern actuator has fault alarm (such as overload, blocking, communication interruption).
