Electric butterfly valves are used in industrial fields, general service fields, water treatment and HVAC and refrigeration industries. The electric butterfly valve has two types of standard "on/off" control and "regulating" control. The electric butterfly valve is simple in structure, small in size, light in weight, and only composed of a few parts. The valve can be quickly opened and closed only by rotating 90 °, which is simple to operate. At the same time, the valve has good fluid control characteristics. When the electric butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. To ensure the normal operation of the electric butterfly valve, the inspection before installation of the electric butterfly valve is essential.

Diverter valves are used to separate, distribute or mix media. Including distribution valves and steam traps of various structures.
