The valve is designed as straight through type and three-way type. The straight through electric ball valve has the lowest flow resistance (actually 0); All sealing materials are imported PTFE, which can be opened and closed flexibly (without lubricant) without jamming. In a large pressure and temperature range, the working medium can be sealed on both sides to achieve complete sealing; The actuator can realize rapid opening and closing, so as to ensure that it can be used in the automation system of the equipment. When opening and closing the valve quickly, the operation has no impact, and the closing part can withstand the high pressure difference during closing, with long service life.
