They are also used in fire protection, water supply, metallurgy, chemical fertilizer, electric power industry, and sewerage of machining industry etc under nominal pressure of CLASS 150-2500LBS and working temperature of -29～℃. They are available in large sizes to better handle thick flow. However, gate valves do have low-pressure limitations, and are not optimal in applications that require cleanliness or sanitary conditions. They are excellent for use anywhere a shutoff valve is needed. They can also be used where throttling capabilities are desired, although this is not generally recommended as erosion of the seat and disc occurs due to the vibrations of the disk in throttling applications.
