產(chǎn)品說明：
一、產(chǎn)品特點(diǎn)：
不銹鋼電動四通換向球閥為X形垂直通道的球閥，它的特點(diǎn)是球體的兩條通道為X形布置，四個通道口徑均布于球體赤道圓周截面上，當(dāng)球體沿順時針旋轉(zhuǎn)90時，能使相鄰的兩個通道實(shí)現(xiàn)兩兩互通。
Features
Four-way direction changeable ball valve is a kind of ball valve with X-pattern vertical bore.It s feature is, the ball valve s two bores
are arranged to be X-pattern ,and its four bores are connected to each other two of adjacent bores can be connected to each other.
