Bevel gear drive soft seal gate valve is one of the commonly used block valves, which is mainly used to connect or cut off the medium in the pipeline; The gate valve is suitable for a wide range of pressure, temperature and diameter, especially for medium and large diameter pipes, and is not corroded by fluid. The relative movement between sealing surfaces is small, and it is not easy to scratch. It is mostly used for medium and large diameter pipes with low, medium and high pressure.
National standard bevel gear drive soft seal gate valve features: smooth passage, small flow coefficient; Reliable sealing, light and flexible operation.

For a long time, the common gate valves used in the market generally have the phenomenon of water leakage or rust. Our company introduces the European high-tech rubber and valve manufacturing technology to produce the elastic seat seal gate valve, which overcomes the defects of poor sealing and rust of general gate valves. The elastic seat seal gate valve achieves good sealing effect by using the compensation effect of the elastic deformation produced by the elastic gate valve, The valve has the advantages of light switch, reliable sealing, good elastic memory and long service life.
The installation and maintenance of gate valve should pay attention to the following matters:
1. Hand wheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
2. The double gate valve shall be installed vertically (i.e. the valve stem is in the vertical position and the hand wheel is at the top).
3. The gate valve with bypass valve should be opened before opening (to balance the pressure difference between inlet and outlet and reduce the opening force).
4. The gate valve with transmission mechanism shall be installed according to the product manual.
5. If the valve is used frequently, lubricate it at least once a month.
Elastic seat seal gate valve has been widely used in various fields such as petroleum, chemical, liquefied gas, water supply and drainage, food, pharmaceutical, power generation, boiler steam system, mining, urban construction, municipal engineering, etc., as well as residents' daily life.
