Groove Type Non Rising Stem Resilient Seated Gate Valve
Product overview
Groove type concealed stem elastic seat sealed gate valve is a kind of soft sealed gate valve, which is a new type of gate valve product produced by introducing foreign technology. It has many advantages that traditional valves do not have and has a wide range of applications. The utility model has the advantages of light switch, reliable sealing, good elastic memory and long service life. The groove gate valve is light in weight, and the body is made of nodular cast iron. Compared with the traditional gate valve, the weight is reduced by about 20%-30%. It is easy to install and maintain. It is widely used in water, sewage, construction, petroleum, chemical industry, food, medicine, light textile, electric power, ship, metallurgy, energy system and other fluid pipelines as regulating and intercepting devices.
Product Features
1. Ingenious opening and closing, convenient and quick installation;
2. In a certain angle range, it can overcome the deviation caused by the different axes connected with the pipeline, and solve the material stress caused by the thermal expansion and cold contraction of the pipeline.
3. The gate valve uses the elastic gate to produce a small amount of elastic deformation compensation to achieve good sealing effect. It has the advantages of light switch, reliable sealing, good elastic memory and long service life. The bottom of the gate valve adopts the same flat bottom design as the pipeline, which is not easy to cause debris accumulation and make the fluid smooth.
4. The valve plate is covered with high-quality rubber, and the rubber and ductile iron valve plate are firmly connected and not easy to fall off
