GENERAL INFORMATION
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.

PATENTED TECHNOLOGY
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.

PERFORMANCE
The graphed performance curve below demonstrates what you would see on a typical thermal actuator performance curve. The variables on the performance curve are: Temperature Range, Extension Stroke, & Return Stroke.

GENERAL INFORMATION
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.

GENERAL INFORMATION
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.

MULTI AXIS & FIVE AXIS CNC MACHINING
We have an array of state-of-the-art CNC machining centers ranging from 3 to 5 axis that enables us to machine without limitations. Typically our manifolds are machined out of aluminum however we are able to process other types of material.

CAD CAM CAPABILITIES
We utilize Solidworks for three dimensional modeling in conjunction with the latest build of MasterCAM to generate our machine instruction and implement rigorous quality control standards aligned with ISO, and AS certification boards. Rostra Vernatherm is a certified ISO 9001 and AS9100 US manufacturer.

GENERAL INFORMATION
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.

GENERAL INFORMATION
Bulb & Capillary thermostats provide system designers the freedom to place system controls in remote locations away from the heat source while still mechanically sensing thermal levels. This class of thermostat relies on a special sealed blend of thermal material within the bulb & capillary assembly to sense heat. Thermal energy "heat" causes the material to expand which opens and closes electrical contacts.
