2-port seat valve is a valve type mainly used in fluid transmission systems to control the flow of liquid or gas. It consists of two main parts, the valve body and the valve seat cushion. Its name comes from its design with two ports - an inlet and an outflow.

The main function of this type of valve is to control the flow between the inflow and outflow ports. It is usually controlled using hydraulic or pneumatic media and can be operated manually or automatically. This type of valve usually won't leak or get stuck because its design is based on good sealing and flow control principles.

The 2-port seat valve has many advantages, the most important of which are its reliability and efficiency. This makes it widely used in various industrial applications, such as chemical industry, food processing, pharmaceuticals and automobile manufacturing. Another advantage is its durability, allowing long-term use without the need for frequent repairs or replacements.

In summary, the 2-port seat valve is a reliable and efficient valve type that can play an important role in a variety of industrial applications. Its development helps improve the performance of industrial control systems and supports the development of industrialization processes.
