Gas/Oil Rotary Actuators Video

https://youtu.be/HWatXH4HTsI Gas/Oil Rotary Actuators use natural gas or nitrogen gas as the motive power and hydraulic oil as the driving medium to actuate the pipeline valve to a fully open or fully closed position.  High-sulfur natural gas and oil pipelines can use nitrogen gas as a power supply. With the bubble tight pneumatic control manifold, the nitrogen bottles only need to be replaced once or twice a year. The electric line break module allows for real time monitoring of pipeline pressure, pressure drop rate, etc.. Learn more about Gas/Oil Rotary Actuators by visiting our CGO Series page.

SIL 3 Safety Rating Lineup Video

SIL stands for Safety Integrity Level and Cowan Dynamics has a range of SIL 3 safety certified actuators to meet Safety Integrity Level requirements for flow control equipment and valve automation.  The concept of safety integrity levels (SILs) is now prevalent in the field of safety-critical systems, and a number of standards advocate its use in the design and development of such systems. This rating is designed to provide customers with reliable actuation solutions in critical applications without compromising their Safety Instrumented Systems (SIS – compliant with IEC 61511/ISA 84). Meeting various national and worldwide standards, SIL has four levels used for rating. The higher the level, the better the system performance.  Assignment of SIL is an exercise in risk analysis where the...
