A corner seat valve is a type of valve commonly used in industrial automation control fields:
Structural Features
Corner seat valves typically consist of a valve body, valve core, valve stem, actuator, and other components. The valve body is angular in structure, allowing for convenient connection to pipeline corners or right angles during installation, saving space and facilitating pipeline layout. The valve core is a key component that controls fluid flow and volume; it is usually made of stainless steel or other corrosion-resistant materials and has good wear resistance and sealing performance. The valve stem connects the valve core and the actuator, transmitting power to achieve opening and closing of the valve core. The actuator can be pneumatic, electric, or hydraulic, with pneumatic actuators being more common, offering advantages such as fast response speed and reliable safety.
Working Principle
Taking a pneumatic corner seat valve as an example, when compressed air enters the actuator's air chamber, it pushes the piston or diaphragm, driving the valve core to open or close through the valve stem. Corner seat valves come in normally closed and normally open types. In a normally closed corner seat valve, the valve core is closed when there is no air source signal; only when compressed air of a certain pressure is introduced will the valve core open, allowing fluid to pass through; the normally open type is the opposite, with the valve core open when there is no air source signal, and closing when compressed air is introduced.
Performance Characteristics
Corner seat valves are compact, small, and lightweight, making them easy to install and maintain. They have good sealing performance, effectively preventing fluid leakage, and are suitable for various fluid media with different pressures and temperatures. At the same time, corner seat valves have a large flow coefficient and strong flow capacity, allowing for rapid on/off control of fluids, with a fast response speed to meet the requirements of precise fluid control in industrial production.
