Q947, Y, F, American standard electric steel natural gas pipeline ball valve for two cut, regulating occasions. The valve and the actuator is connected by direct connection, electric actuator servo system built-in, without the servo amplifier, the input4-20mA signal and220VAC power supply control operation. With a simple wiring, compact structure, small size, light weight, small resistance, the advantages of stable and reliable action. The actuator can be configured according to user requirements, the other UNIC PSQ, HQ, DHL and other types of electronic type electric actuator or GTX, AL gas piston type actuator.

Ball valve in the oil, natural gas, coal and ore extraction, refining and pipeline systems; in the chemical products, pharmaceutical and food production; in hydropower, thermal power and nuclear power production system; in the city and industrial enterprises in the water supply and drainage, heating, and gas supply system; in farmland irrigation and drainage system; in metallurgical production system is widely used, is a production and construction, national defense construction and people life be closely bound up the important mechanical products. Ball valve closed in piping system for cutting off or switching on media stream, the medium according to a predetermined program delivery to the designated point.
