Products Details

Soft seal gate valve is a kind of valve that uses soft sealing material to achieve sealing effect. It has the advantages of lightweight, good sealing, strong elastic memory and long service life. This valve is widely used in tap water, sewage, construction, food, power, medicine, metallurgy, textile and energy systems and other fields, as a fluid pipeline on the adjustment and cut-off device.
​
The features of the soft seal gate valve include an integral rubber coating to ensure a reliable seal and long service life; The valve body adopts ductile iron, light weight and easy to install; Flat bottom seat design, prevent debris deposition, improve sealing reliability; Good corrosion resistance, the inner cavity is coated with non-toxic epoxy resin to prevent corrosion and rust, suitable for drinking water and sewage systems; The valve stem is designed with three "O" seals to reduce friction resistance during switching for light operation and no water leakage.
​
In addition, the internal and external use of non-toxic coating resin, enhance the anti-corrosion ability, eliminate the secondary pollution of water quality. The stem nut is embedded in the valve body and is not easy to loosen or corrode, extending the service life. Three "O" sealing ring design for easy water replacement and maintenance.
​
The parameters of the soft seal gate valves include calibers from DN15 to DN80, pressure classes from PN10 to PN16, and connection methods are threaded or internal. The body material can be cast iron, ductile iron, cast steel or stainless steel, and the gate is usually made of ductile iron lined with butadiene rubber. Applicable temperature range from -40℃ to 120℃, suitable for water, oil, natural gas and other non-corrosive fluids.
​
The use of soft seal gate valves includes some famous buildings and enterprises, such as Burj Khalifa in Dubai, Taipei 101 Tower, Shanghai World Financial Center, Petronas Tower in Kuala Lumpur, Sears Tower in Chicago, Shenzhen Jingji 100, Shanghai Jinmao Tower and Hong Kong International Finance Center II.
