① The friction between the sealing surfaces is small during the opening and closing process

② Relatively durable. 

③ The opening height is not large. 

④ Easy to manufacture. 

⑤ Easy to maintain. 

⑥ Not only suitable for medium and low voltage, but also for high voltage. The closing principle of a DC globe valve is to rely on the pressure of the valve stem to tightly fit the sealing surface of the valve disc and the sealing surface of the valve seat, preventing the flow of the medium. The shut-off valve only allows one-way flow of the medium and has directionality during installation. The structural length of the globe valve is greater than that of the gate valve, and the fluid resistance is high. During long-term operation, the sealing reliability is not strong.
