1. Product overview of Q941-FB electric explosion-proof ball valve :
The Q941-FB electric explosion-proof ball valve produced by Shanghai Wuyue is a valve that rotates 90° around the axis perpendicular to the channel. It is composed of a rotary angular stroke electronic electric actuator and an O-shaped ball valve structure. It is a high-performance rotary type. Regulating or switching type cut-off valve, accepting the input and output of current signal or voltage signal from industrial automation control (DCS, PLC system) instrument source, can realize the proportional adjustment or two-position switch control of the fluid medium in the industrial pipeline, so as to achieve the Automatic control of parameters such as flow rate, pressure, temperature, and liquid level of the fluid medium.
2.Features of Q941-FBproduct:
1. Explosion-proof electric ball valve has low fluid resistance, which is the smallest fluid resistance of all valves. It is powered by AC220V, AC380V or DC24V power supply voltage and accepts (4-20mA, 0-10mA or 1-5VDC) current signal or voltage The signal can be used to control the operation, and the sphere can be rotated 0~90° with the torque output by the angular stroke to complete the opening and closing actions or adjustment actions.
2. The fully electronic electric actuator adopts an organic-electric integrated structure. It has functions such as internal servo operation and position feedback of the opening signal, position indication, and manual operation. It has strong functions, reliable performance, and simple connection. It can input current signal or voltage Signal, change the rotation angle of the ball core (any angle of 0-90°) to realize the proportional adjustment action.
3. The ball core channel is flat and smooth, and it is not easy to deposit media, and can be used for pipeline ball passing. Simple structure, light weight and good sealing performance. Especially suitable for occasions requiring zero leakage rate.

The company's electric explosion-proof ball valve is composed of a quarter-stroke explosion-proof electric actuator and a ball valve sphere. It is composed of an electronic quarter-stroke electric actuator 3610R or HQ series and a ball valve adjustment mechanism. Electric explosion-proof ball valve has the characteristics of simple structure, fast switching, large circulation capacity, zero leakage, etc., suitable for high-viscosity, fiber-containing, solid particle fluid occasions, explosion-proof electric ball valve is mainly used in petrochemical, metallurgy, light industry and other industrial automation control The field cuts off or circulates the medium in gas and liquid pipelines. The actuator adopts an integrated design, input 220V power supply can directly carry out on-off adjustment, can also be built-in servo module, input control signal (4～20mADC or 1～5VDC) and single-phase power supply can control operation. The explosion-proof grade of the electric explosion-proof ball valve is ExdⅡBT4, the protection grade is IP67, and it can be equipped with on-site control devices. The main features of the explosion-proof electric ball valve are: when the power is off, the clutch handle can be manually operated. When energized, the clutch automatically resets. The flow direction can be arbitrary, the adjustable range is large, and it can be used in high pressure and large diameter occasions to control high viscosity, fiber and fine particle media.
