The electric ball valve is composed of an electric actuator and a ball valve. It is a kind of pipeline pressure element for industrial automation process control, which is usually used for remote opening and closing (on, off and off medium) control of pipeline media. Here is an introduction to the commonly used electric ball valves. 
Introduction to Seven Commonly Used Electric Ball Valves:
1. Q941F electric flange ball valve: Q941F electric flange ball valve is suitable for two-position cut-off and adjustment occasions. The connection between the electric on/off ball valve and the actuator adopts the direct connection mode, and the electric actuator has a built-in servo system, which can control the operation without the need for a servo amplifier, and the input of 4-20mA signal and 220VAC power supply. It has the advantages of simple wiring, compact structure, small size, light weight, low resistance, stable and reliable action, etc. 
2. Q911F Electric Internal Thread Ball Valve: Q911F Electric Internal Thread Ball Valve is composed of fine and small electric actuator and stainless steel internal thread ball valve, and the ball valve body can be divided into one-piece, two-piece and three-piece type, which is or 316L stainless steel material silica sol precision casting. The valve seat adopts PTFE elastic sealing structure, which is easy to open and close and reliable to seal. It is suitable for water, steam, oil, nitric acid, acetic acid and other media. 
3. Q971F electric ultra-thin ball valve: electric ultra-thin ball valve (electric clamping ball valve) is composed of DSR electric actuator and ultra-thin ball valve, electric ultra-thin ball valve (electric clamping ball valve) and ordinary electric ball valve compared with the ordinary electric ball valve has the characteristics of compact structure, small size, light weight, close distance between the valve seat and the end face flange, less material retention, superior sealing performance, etc. Generally, the electric pinch ball valve is suitable for occasions with a relatively short installation position, and is widely used in automatic control in chemical, petroleum, pharmaceutical, light industry and other industries. The V-channel sphere structure is used to match with the electronic electric actuator, which can realize the adjustment of the flow rate. 
4. Q944F and Q945F electric flange three-way ball valves: Q944F and Q945F electric flange three-way ball valves take AC220V single-phase alternating current as the power source, accept the 220V switch signal from the control system (or operator), and drive the reversible single-phase gear reducer motor through single-phase power switching, so that the ball valve can realize the reversing effect on the pipeline fluid according to the specified combination requirements. 
5. Q914F, Q915F electric three-way internal thread ball valve: The electric three-way internal thread ball valve is composed of DSR series quarter-turn electric actuator and internal thread three-way ball valve, which is a rotary cut-off and regulating valve, which has the advantages of tight closing, compact structure, light weight and convenient maintenance. The electric three-way internal thread ball valve takes 220V single-phase alternating current as the power source, accepts the switching signal of the control system, and drives the reversible single-phase gear reducer through single-phase power switching, so that the ball valve switches the pipeline according to the specified requirements. 
6. Q947F electric fixed ball valve: Q947F electric fixed ball valve adopts an integrated structure, with input control signal (4 20mA DC or 1 5V DC) and single-phase power supply to control the operation, with strong function, small size, light and cheap, reliable performance, simple matching, circulation capacity, especially suitable for the medium is viscous, containing particles, fiber nature of the occasion. At present, the valve is widely used in industrial automatic control systems in food, environmental protection, light industry, petroleum, papermaking, chemical teaching and scientific research equipment, electric power and other industries. 
7. Q941F46 electric fluorine-lined ball valve: Q941F46 flanged electric fluorine-lined ball valve is composed of electric actuator and straight-through two-point casting fluorine-lined ball valve, because the valve cavity and ball are made of high-pressure injection molding process, lined with corrosion-resistant, anti-aging PTFE propylene (referred to as F46), so it has reliable corrosion resistance and sealing, and the actuator can provide sufficient rotation distance to ensure the reliable opening and closing of the valve, and has an automatic reset clutch, which can be automatically reset when the power is lost. The built-in valve position feedback device can realize the transmission and remote control of the valve position signal.
