Application
▪ For a long time, the common used gate valves in the market generally have the phenomenon of water leakage or rust. European high-tech rubber and valve manufacturing technology was introduced for our this soft seal gate valve, which has overcome the defects of poor sealing, elastic fatigue, rubber aging and rust of ordinary gate valves.
▪ The soft seal gate valve uses the compensating effect of slight elastic deformation produced by the elastic valve disc to achieve good sealing effect. The valve has the remarkable advantages of light switching, reliable sealing, good elasticity and long service life.
▪ It can be widely used in tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, electric power, shipping, metallurgy, energy system and other fluid pipelines as regulating and intercepting devices.
