Electric flange ball valve is driven by the power supply to operate the valve opening and closing and medium size adjustment, sealing structure can be divided into soft seal and metal hard seal, suitable for different working conditions and media.
电动法兰球阀是依靠电源驱动来操作阀门的启闭与介质大小的调节，密封结构可分为软密封和金属硬密封，适用于不同的工况及介质当中。
So what are the advantages of electric flange ball valves?
那么大家知道电动法兰球阀的优点是什么？
The advantages of electric flange ball valve are as follows:
电动法兰球阀的优点如下：
1, the electric actuator built-in servo system, without additional servo amplifier, input and output signal 4-20mA and AC380V power supply can control the operation.
1、电动执行机构内置伺服系统，无须另配伺服放大器，输入输出信号4-20mA及AC380V电源即可控制运转。
2, according to the needs of the working condition, choose explosion-proof type, or assemble the hand wheel device, to realize the function of manually switching the valve.
2、根据工况需要选用防爆型，或装配上手动手轮装置，实现手动开关阀门的功能。
3, electric flange ball valve flow resistance is very small, large flow capacity, easy loading and unloading maintenance, good sealing performance, suitable for a variety of working conditions.
3、电动法兰球阀流阻力超小、流通能力大、装卸维护方便、密封性能佳，适用于多种工况。
4, Q941H electric ball valve small size, light weight, large thrust, servo amplifier installed, easy to operate, high reliability.
4、Q941H电动球阀体积小、重量轻、推力大、伺服放大器内装、操作方便、可靠性高。
5, the electric flange ball valve flow direction can be arbitrary, wide adjustable range, can be used for high pressure and large diameter occasions, control high viscosity, with fiber and fine particles of the medium.
5、电动法兰球阀流向可任意，可调范围广，能用于高压和大口径场合，控制高粘度，带有纤维和细颗粒的介质。
6, can be applied to two off control occasions, can also be the medium flow pressure temperature and other parameters for percentage adjustment.
6、可适用于两位关断控制的场合，亦可对介质流量压力温度等各项参数进行百分比调节。
