What to consider when choosing a suitable resilient seated gate valve

The soft-seal /resilient seated gate valve is widely used. It is favored by users because it overcomes the product defects such as poor sealing and rust of ordinary gate valves. The soft sealing gate valve has a unique elastic seat seal to achieve a good sealing effect. The soft sealing gate valve is easy to open and close, reliable in sealing, good elastic

memory and long service life. It can be widely used as a regulating and intercepting device on the pipelines of tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, electric power, shipbuilding, metallurgy, energy system, etc.
To choose a resilient seated gate valve, you must first select the corresponding product according to the use environment, that is, the difference in the medium. Followed by some other technical parameters such as specifications, models and pressures. The correct selection can ensure the performance characteristics of the soft seal gate valve to the extreme, as well as the good operation of the pipeline, extend the service life of the pipeline, pump, and valve, and achieve the expected use effect of production. There are many types of rubber, but the best and economical ones are nitrile rubber and natural rubber. As an elastic sealing pair, they have high elasticity, high tensile strength, good abrasion resistance and drought resistance. Operating temperature range: about -60℃～80 ℃ Non-corrosive or general corrosive medium, can be water, gas, etc.
Soft seal gate valve, the inner cavity surface of the valve is not lined or covered with various rubbers, suitable for various working temperatures and fluid pipelines. Relatively speaking, as a resilient seated gate valve, rubber gate valves are not as resistant to high temperature and corrosion as fluorine-lined gate valves, which is a disadvantage of rubber seals. Fluorine-lined gate valve, also known as fluoroplastic-lined corrosion-resistant valve, is to place PTFE resin on the inner wall of steel or iron valve pressure-bearing parts or the outer surface of valve inner parts by moulding or inlaying, and use it in The unique performance of anti-corrosive medium is made into various valves.
When choosing a resilient seated gate valve, you must fully consider the main issues of medium, temperature, pressure, caliber, etc., to ensure that the use of the valve conforms to the working conditions and the characteristics of the product itself, and to maintain the service life.
