Description

The QT series quarter-turn valve electric actuator can operate with butterfly valve, ball valve and cock valve and other kinds of quarter-turn valves. It is compact and light, which is featured by high efficiency, high reliability, high protection class and 1ow noise. Both remote control and local control are available. This product has been applied to many fields, such as petroleum, chemicals,electricity, water treatment and paper-making industry.

[Working Environment and Main Technical Parameters]

--Optional power supply: AC 220 V AC 380 V.

--Ambient temperature :-25 C~+70 C.--Protection level: IP 67.

--Relative humidity:< 90% ( at 25 C).

--Working time: Short time of 10 min.

The foot plate type QT angular stroke electric actuator is connected to the valve and other equipment as a wall foot plate type. The imported series of electric actuators are suitable for part turn valves (such as butterfly valves, ball valves and dampers, etc.), and imported electronic components are used. , High-quality aluminum alloy die-casting shell, fine and smooth, small size, light weight, maintenance-free, strong corrosion resistance and other excellent performance, can be used in narrow places. The products are widely used in building automation, water conservancy, papermaking, electric power, chemical industry and other automatic control systems, power equipment, environmental protection chemical industry, thermal power industry, petrochemical industry, pipeline engineering, water conservancy engineering, valves, dampers and other industries.
