1. Q941F electric flanged ball valve: Q941F electric flanged ball valve is suitable for the occasion of two-position cut-off and adjustment. The connection between the electric on-off type ball valve and the actuator adopts the direct connection method. The electric actuator has a built-in servo system, and does not need to be equipped with a servo amplifier. Input 4-20mA signal and 220VAC power supply to control the operation. It has the advantages of simple connection, compact structure, small size, light weight, low resistance, stable and reliable action, etc. Product name Electric flanged ball valve Product model Q941F Product diameter DN15-DN300 Product pressure 1.6MPa-6.4MPa Product material The ball valve body can be divided into one-piece type, two-piece type and three-piece type. The valve seat adopts PTFE elastic sealing structure, which can be opened and closed easily and reliably. Suitable for water, steam, oil, nitric acid, acetic acid and other media. Product name Electric flange ball valve Product model Q911F Product diameter DN6-DN100 Product pressure 1.6MPa-6.4MPa Product material Carbon steel, stainless steel Three, Q971F electric ultra-thin ball valve: electric ultra-thin ball valve (electric wafer ball valve) by DSR It is composed of electric actuator and ultra-thin ball valve. Compared with ordinary electric ball valve, electric ultra-thin ball valve (electric wafer ball valve) has compact structure, small volume, light weight, close distance between valve seat and end face flange, less material retention and sealing. Features such as superior performance. Generally, electric wafer ball valves are suitable for occasions where the installation position is relatively short, and are widely used in automatic control of chemical, petroleum, pharmaceutical, light industry and other industries. The V-channel sphere structure and the electronic electric actuator can be used to realize the adjustment of the flow. Product name Electric ultra-thin ball valve Product model Q971F Product diameter DN15-DN150 Product pressure 1.6MPa-6.4MPa Product material Carbon steel, stainless steel four, Q944F, Q945F electric flanged three-way ball valve: Q944F, Q945F electric flanged three-way ball valve AC220V single-phase alternating current is the power source, accepts the 220V switch signal from the control system (or operator), and switches the single-phase power supply to drive the reversible single-phase gear reducer motor. commutation effect. Product name Electric flanged three-way ball valve Product model Q944F/Q945F Product diameter DN15-DN250 Product pressure 1.0MPa-6.4MPa Product material It is composed of DSR series angular stroke electric actuator and three-way ball valve with internal thread. The electric three-way internal thread ball valve uses 220V single-phase alternating current as the power source, accepts the switch signal of the control system, and drives the reversible single-phase gear reducer through the single-phase power switch, so that the ball valve can switch the pipeline according to the specified requirements. Product name Electric flange thread ball valve Product model Q914F/Q915F Product diameter DN15-DN50 Product pressure 1.0MPa-6.4MPa Product material Control signal (4~20mA DC or 1~5V DC) and single-phase power supply can control the operation. It has strong function, small size, light and cheap, reliable performance, simple matching, and flow capacity. It is especially suitable for viscous media. Occasions containing particles and fibers. 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. Product name Electric flange threaded ball valve Product model Q947F Product diameter DN50-DN1000 Product pressure 1.6MPa-10MPa Product material Carbon steel, stainless steel Seven, Q941F46 electric fluorine-lined ball valve: Q941F46 flange electric fluorine-lined ball valve It is composed of a split cast fluorine-lined ball valve. Since the inner cavity and the ball of the valve are made of high-pressure injection molding process, they are lined with corrosion-resistant and aging-resistant PTFE (F46 for short), so they have reliable corrosion resistance and sealing performance. The actuator can provide enough torque to ensure reliable opening and closing of the valve, and has an automatic reset clutch, which can automatically reset when power is lost. The built-in valve position feedback device can realize the transmission and remote control of the valve position signal. Product name Electric flange thread ball valve Product model Q941F46 Product diameter DN50-DN400 Product pressure 1.6MPa Product material Carbon steel, stainless steel
