Intelligent anti-riot electric actuator

QT series partially rotary valve electric device is an independent partially rotary product developed by our company on the basis of synthesizing the characteristics of similar products at home and abroad. It is suitable for controlling butterfly valves, ball valves, plug valves and other valves that do 90 ° rotation. It can be operated on site or controlled from a distance. The product can be widely used in petrochemical, metallurgy, shipping, light industry, food, paper, construction, municipal engineering, thermal power and hydropower and other industrial fields that use pipeline valves.

The technical performance of QT series products is in line with the provisions of JB/T8528 - 1997 "General type valve electric device technical conditions", and in line with the relevant standards and industry standards.

The basic type of QT series products is outdoor type, and its protection level is IP67 (higher protection level can be proposed at the time of ordering). The products can also be made into explosion-proof type, the user should be proposed at the time of ordering, explosion-proof type of basic technical parameters and flange structure dimensions and the content of the sample is the same, but explosion-proof products, models, specifications, external dimensions, structural type, explosion-proof level and performance should be referred to the company's explosion-proof product samples.
