Whether you need to open or close a valve, operate a switch, or create a motion driven by temperature, Keystone can provide you a custom designed thermal product for your application.
Thermal actuators are the primary component of any wax based thermostat. They are usually supplied as part of an assembly but can be sold by themselves.

Our control valves are designed to regulate, bypass, or shutoff flow based on temperature.
Simplified Automation and Control
By incorporating a thermal actuator into our valves we create a smart valve. These valves can automate and regulate flow requirements without the need for a power source, electronics, or computer programming. The reliability and repeatability of Keystone’s valves along with their low cost make them a top choice for engineers and manufacturers everywhere.

Spring Return Assemblies
The spring return assembly is the best method of incorporating the thermal actuator into the customer’s product or assembly. Customers can use our custom design, or we can design one to work with new or existing assemblies.
