Flange gate valves are the gate valves with flange connections, which are common in our daily life. The flange gate valve is stable and reliable when it is used in the pipeline, and it can't be used in the high-pressure pipeline.
A high pressure national standard cast steel gate valve is suitable for the conversion of nominal pressure from 4.0 MPa to 10.0 MPa (1 MPa = 10 kg), and the working temperature is from - 29 ℃ to 600 ℃ in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power industry and other working conditions. The medium in the pipeline can be cut off or connected without adjustment and throttling. Suitable media are water, oil, steam, acid medium, etc.
For a long time, the general gate valve used in the market has the phenomenon of water leakage or rust. The elastic seat seal gate valve produced by our company has overcome the defects of poor sealing and rusting of general gate valves by introducing high-tech rubber and valve manufacturing technology from Europe. The elastic seat seal gate valve achieves good sealing effect by using the compensation function of elastic gate valve to produce a small amount of elastic deformation The gate valve has the advantages of light weight, reliable sealing, good elastic memory and service life. It can be widely used in tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, electric power, ship, metallurgy, energy system and other pipelines as regulating and intercepting devices.
The main design features and advantages of flange gate valves are as follows:
Light weights: its weight is amost the same with traditional valves and it needs about 20% to 30% of the installation and maintenance.
Flat doors: traditional national pipe and valve cleaning is mainly for foreign matters such as stone, wood, cement, iron filings and other debris deposited at the bottom of the groove. After passing through, it is easy to form a flow rate close to waterproof. The design and use of the same unit at the bottom of the flexible seal valve seat can easily cause the accumulation of debris and make the fluid unobstructed.
General plastic bag: rubber doors have overall high quality. European leading technology allows rubber vulcanization of the door after vulcanization to ensure the correct geometry of the rubber. The smart door is strong, not easy to drop and has good elastic memory.
Cast body water: the body is adopted by precision cast, with the shape of geometry. Then, there is no any internal finish to ensure the sealing performance of stainless steel gate valves.
