Accessories include components or systems that increase or extend the functionality of products. A great example of an accessory is the 2A1279. It is an electromechanical air-operated relief valve designed to provide overpressure protection for pressure vessels, tanks, and other pressurized containers.

2A1279 application field mainly includes pressure volume chambers, pipelines and mechanical equipments, along with factories engaging with 3C industry, petrochemical fractionation, petroleum storage and power grid pressure limiting. With its distinguished characteristics of simple structure and light weight, they are applied to prevent overpressure in low temperature and small pressure difference.

The working principle of 2A1279 is based on electromechanical transduction. It use electricity to respond to pressure change from external sources, and then convert pressure energy into mechanical energy as motion to drive other objects. When the pressure inside the device exceed the set valve, the overloaded helium spring of 2A1279 will begin to heat and expand, and then displace the position of the controlling element. This, in turn, causes the spring loaded pilot valve to open, allowing pressure to flow from the inlet side to the outlet side, since the resistance the pilot valve has to encounter becomes reduced. The entire process reduces the pressure, ultimately resulting in safety protection.

It is a widely used safety device due to its reliability and cost effectiveness. Besides being resistant to large pressure differences, its components that come in contact with flow media are made of special materials, allowing corrosive and non corrosive liquids, as well as thermal and hypothermal gases. Those characteristics, plus its ability to work reliably in a wide range of temperature, allows its use in very dangerous areas, such as chemical plants, oil refineries, and nuclear power plants.

In conclusion, the 2A1279 is a valuable and safe accessory with a number of applications. It provides an optimized solution for overpressure protection in a variety of contexts, with suitable components available for all sorts of unique cases, making it reliable, efficient and cost-effective.
