Vernatherm Control Valves provide customers with automated, non electric, thermally activated system control. Vernatherm specializes in controlling several variables within many industrial systems. We can isolate and control one variable, or blend several to create a multifaceted solution. Some of our valves require a housing / manifold while some are self contained. If the valve you need requires a manifold, Rostra Vernatherm can ensure maximum performance through machining a manifold specifically for your valve.
Non-Electric Thermal Activation
Thermally activated, hydrocarbon powered control devices used in various control applications.
Our thermal activation devices react to thermal energy within your existing system through the use of thermal actuators, and power products such as diverter, and temperature regulating valves.
