A thermally activated valve provides reliable, automated, and non electric solutions for control through thermal expansion. In real-time our thermal valves monitor temperature within applied systems and perform the tasks of port diverting, mixing, and or port modulation. Our thermal valves can also be paired with pressure regulating features if required. Some of our valves require a housing manifold while others are self contained in a simple multi-port body. If the valve you need requires a manifold Rostra Vernatherm will ensure maximum performance through machining a manifold specifically for your needs; see more on manifolds here.

Available in a variety of sizes and configurations, our thermal actuators all function through thermal expansion. Our thermal actuators can be utilized in limitless applications from miniature to heavy duty. Our fast acting self-actuating actuators provide precise pushing forces and accurate travel distances.

Our pressure relief controls can manage pressure as a single purpose valve, or can be paired with a thermal control unit. Our pressure relief valves span from small precise units that are utilized in the aerospace industry all the way to simple freeze protection devices for residential and commerical building projects. The controls featured on this page are set in-house to your secific requirments. We offer several types of pressure relief valves please read below for more details on those specific types.

Conduction type thermostats are a type of thermostat that sense temperature through thermal conduction, meaning they are mounted on a surface that will output heat and they will react. We offer three classes of conduction type thermostats; adjustable, fixed & sealed, and fixed wout sealing. These devices are used widely within industrial applications that require thermal control in electrical appliances, food service equipment, industrial drum heaters, laminators, etc. These devices permit electrical continuity below the set temperature and prohibit continuity when the set temperature is reached.

Open Air Thermostats are classified as our A-5011 series units and they are as versitile as our B200 closed body conduction type thermostats. The only difference between the conduction type and the open air type is the way they sense thermal energy. Open air thermostats sense temperature through convection rather than conduction. Snap Disc Thermostats are classified as our A-5000 series; spanning from 5001 through 5008. Each part number in the series represents a different thermal shut off temperature. The A-5000 units feature a bimetallic, temperature-sensitive disc that snaps openclose switch contacts disruptingre-estabishing continunity.

Manifolds are simply machined housings that contain valve and or actuator (wax motor) technology. These necessary components provide the environment for our valves and actuators. Manifolds are machined to provide proper porting that will ensure compatibility within your system, fluid control ports can be machined in any configuration you require.
