(6) Having the ability to accurately control fluids within a mechanical system can mean the difference between a long running success and a short lived disaster.
Rostra Vernatherm Oil Valves can give your system the accurate control necessary to assure proper flow direction.
Function Availibility: (choose 1 or all 3 functions)
(8) Available in a variety of sizes and configurations, Vernatherm actuators may be applied in a variety of different applications. Sizes range from light to heavy duty units. Whatever the size, these fast acting thermal actuators produce high forces and long travel distances, enabling the effective control of your system. Our custom expansion material blend gives us an edge over our competitors standard operating temperatures. When you choose Rostra's thermal actuators, the customer is in complete control of the temperature and range needed. You can choose any temperature and range from 30F to 300F which is the largest selection available today.
(5) Rostra's pressure relief valves can be specifically designed for cracking pressure 15 PSI and higher. Our CNC manufacturing equipment allows these valves to be produced in a variety of corrosion resistant metals including brass, aluminum, and stainless steel with tolerance capabilities to +/- .0005" (.0127mm). Closer tolerances may be obtained through secondary operations.
Our standard range of pressure valves include:
Adjustable Type Designs
Poppet Type Designs
Cartridge or Insert Type Designs
Adjustable Type
Adjustable Crack Pressure from 500 PSI to 2000 PSI
Conventional metallic thermostats have their limitations, especially over a long period of time. Corrosion will breakdown its structural integrity leading to failure and system damage.
We have significantly decreased replacement times by redesigning and injection molding the main body and valve of our thermostats with a durable corrosion free plastic material.
Protect system fluid from freezing with Rostra Vernatherm's freeze protection valves.
Vernatherm freeze protection valves use reliable, non-electric, self-contained Vernatherm paraffin wax motors (thermal actuators) which automatically respond to temperature fluctuations. Usually in freeze protection applications, the valve port opens on temperature drop, allowing liquid that would normally freeze to be discharged and replaced with warmer fluid within the system. When warmer temperatures are detected by the thermal actuator within, the valve will automatically close the valve and the discharge cycle stops.
