软密封闸阀
Soft seal gate valve , the substitute product of traditional gate valve, can achieve sound sealing performance by the compensation function of micro deformation of elastic gate valve. As it is superior for its light and flexible switch, reliable sealing, excellent elastic memory and long service life, the valve can be widely applied to fluid pipeline, including tap water, polluted water, buildings, food, electricity, medicine, metallurgy and light textile, as adjustment and closure equipment.
