Contact usThe forged steel internal thread and socket welding gate valve has small fluid resistance and requires small torque for opening and closing. It can be used on the ring network pipeline where the medium flows in two directions, that is to say, the flow direction of the medium is not restricted. When fully open, the sealing surface is less eroded by the working medium than the globe valve. The body structure is relatively simple, the manufacturing process is good, and the structure length is relatively short. It is suitable for industrial pipelines in steel plants, petroleum, chemical industry, gas, boilers, papermaking, textiles, food, ships, water supply and drainage, energy, polysilicon, electric power and other industries.
