Spirax-Sarco temperature control valves are self-acting valves to control the temperature in steam systems. A change in temperature at the sensor will cause the liquid filling to expand or contract. If the liquid expands it will apply a force on the thrust pin which, in turn, will cause the valve plug to move. As the liquid contracts the force on the valve plug reduces and a spring reverses its direction of travel. For heating applications the valves will be normally open and will close against a rise in temperature. For cooling applications the valves will be normally closed and will open against a rise in temperature.
