When a thermal actuator is exposed to drops in temperature, the thermal-sensitive materials inside contract, allowing the piston to retract. Stroke refers to the distance a piston travels outward from a linear actuator. Many of the more common thermal actuators feature pistons that can extend between 0. Most thermal actuators are made to react to temperatures anywhere between 86 degrees Fahrenheit 30 degrees Celsius and degrees Fahrenheit degrees Celsius.
Manufacturers produce thermal actuators in a wide range of sizes and options, making them ideal for many different applications. Many thermal actuators are designed for use in pressurized or vacuum, gas, or liquid environments. They can be built out of durable, rugged materials such as aluminum, brass or stainless steel and feature custom mounting configurations.
Thermal actuators are easily machined and can be designed to feature any thread type or valve end. Our fast acting self-actuating actuators provide precise pushing forces and accurate travel distances. Our patented high performance expansion material and willingness to blend you any temperature you want sets us apart from our competitors' inflexible policies and limited thermal abilities.
With our actuators you are in complete control over what temperature range they perform at and to what degree. Every actuator we design is for the customer and to the customer's specifications. The graphed performance curve below demonstrates what you would see on a typical thermal actuator performance curve. We also can accommodate any fastening method you need, standard threads, snap rings, custom design etc.
If you are unsure of what you need simply let our team of engineers work with you to solve your problems.
Prior to any commitment we can provide samples for you to evaluate and qualify, giving you the confidence needed to move forward with your project. When requesting a quote simply let us know how you want your thermal actuators to function based on the three performance ranges listed on the left and our engineers will guide you the rest of the way.
Initial Altitude: The initial altitude of the piston measured from a reference level when it is static. Full opened Stroke: The displacement of piston from initial altitude under the full opened temperature.
Overstroke: The displacement of piston from initial altitude under utmost working temperature. Hysteresis: The disparity between the temperature rise curve and temperature drop cooling curve of thermostatic elements, which is decided by the composition of wax.
Sensitivity: The time when the top of piston up to the full opened stroke under certain temperature. Structural Features Advantages: Larger stroke distance, higher reliability, the preferred choice for engine thermal management system. Structural Features Advantages: Precise movement path, high sensitivity, the preferred choice for sanitary applications and heating system.
Structural Features Advantages: Large stroke, big absorbing load, small volume, generally used in engine cooling system or some other special application.
