Metal Seated Gate Valve

Metal seated gate valve adopts brass material as sealing. Compared with resilient seated, its wear and corrosion resistance performance is better, which greatly prolongs the service life of gate valve. It can be widely used in tap water, sewage, construction, food, electric power, medicine, metallurgy, light textile, energy system and other fluid pipeline as a regulating and closure device.
