The valves made by pressure relief valve manufacturers are popular and widely used in the diagonal process as well as in our daily life. We will be familiar with them for their daily use for LPG stoves and water taps. And considering the various machines like gas engines, compressors, pumps and vehicles, the inevitable parts are valves.
About 4000 years ago, Chinese people learned to use something like bamboo or corks in water pipes to control the flow of water. And with the development of smelting technology and hydraulic machinery, kinks are replaced with copper plugs in Europe. Widespread use of boilers, levers and weight protection came into being in 1681. In addition, the invention of steamer is applicable in the mechanical industry. At this time, butterfly and slide valves are used to control the flow and meet the higher requirements. Later, a stop valve with threaded idle threaded stem with threaded stem and gate valve is discovered that is adapted to a more and more complex working condition. And in World War I, many new technologies have been introduced, introducing valve production to a new level.
Generally, they are devices used to control the flow rate, pressure or directional flow of liquids, gases, gas - liquid mixtures or solid - liquid mixtures built by the safety relief valve manufacturers. They usually have valve body, bonnet, seat, lifting parts, drive mechanism, seal and fastening parts.
