Product Overview:
Soft seat gate valves are the replacement of the traditional gate valves, using the compensation action of flexible disc making trace deformation to achieve good sealing effect. This kind of valve has the outstanding advantage of overall rubber coating, anti corrosion, nonbreakable, good elastic memory and long service life etc. It can be widely used on tap water, sewage, construction, food, electric power, medicine,metallurgy,light textile .energy system and other fluid on the pipeline as the adjusting and the closure device.
