The effect of temperature on air control valve

Temperature is a key operating environment factor that affects air control valve performance and reliability. Extreme temperatures can adversely affect valve materials, seals, and internal components, resulting in valve failure or reduced control accuracy.

Effect of High Temperature on Air Control Valve
High temperature will cause the valve body material to expand, which may cause the valve body to deform, affect the cooperation between the valve core and the valve seat, and reduce the sealing performance of the valve. In addition, high temperatures will cause the seal material to deteriorate or harden, losing elasticity and sealing properties, causing valve leakage or failure. At the same time, high temperature will also cause the lubricant inside the valve to deteriorate or volatilize, increase the friction between the valve core and the valve seat, and affect the valve's response speed and control accuracy. In addition, some electronic components in air control valves, such as sensors and controllers, are sensitive to high temperatures. High temperatures can cause these components to malfunction, affecting the normal operation of the valve.

Effect of low temperature on air control valve
Low temperature will thicken the lubricant inside the valve, increase the friction between the valve core and the valve seat, and affect the valve's response speed and control accuracy. In addition, low temperatures can cause seal materials to shrink, potentially causing seal failure and causing the valve to leak or fail. At extremely low temperatures, ice may form between the valve plug and valve seat, causing the valve to stick or fail. In addition, low temperatures can cause some valve materials to become brittle and prone to cracking or damage.

Responses
In order to reduce the impact of temperature on air control valves, we can take the following countermeasures: Choose high temperature/low temperature resistant materials to ensure that the valve can still work properly under extreme temperature conditions. At the same time, use high temperature/low temperature resistant lubricants to ensure that the valve can still maintain good lubricity under extreme temperature conditions. In low-temperature environments, take insulation measures, such as installing insulation layers or heaters, to prevent valves from freezing. In addition, choosing an air control valve with temperature compensation function can automatically compensate for the impact of temperature changes on valve characteristics and ensure valve control accuracy.
