Why Heat Extension Kits are Critical for Protecting Actuators
When valves are exposed to hot media such as steam, condensate, or high-temperature gases, the extreme heat can quickly transfer up through the mounting interface and into the actuator, leading to premature failure, degraded performance, or even total breakdown.
Heat Extension Kits create a vital thermal barrier by elevating the actuator above the heat source—physically separating the actuator from the valve body and media path. As a general rule of thumb, for every 10 cm of vertical elevation, you can reduce the heat exposure by up to 100°C. This dramatic temperature drop plays a crucial role in extending actuator lifespan, maintaining internal electronics, seal integrity, and actuator torque output.
In applications involving steam lines or thermal oil, this simple yet highly effective spacing solution is essential for ensuring long-term reliability, reducing downtime, and avoiding expensive actuator replacements.
Without a heat extension kit, actuators are forced to absorb constant thermal stress, which can lead to warped components, damaged internals, or failure of electronics. By adding even a small vertical gap, you significantly reduce heat transfer—turning a high-risk setup into a controlled, protected assembly that performs reliably under pressure.
