A general-purpose globe valve actuator using shape memory alloy (SMA) technology has been recently introduced to the industry.

Asahi/America, Inc., a leader in thermoplastic fluid flow technology, has recently expanded its Series 19 electric actuation line to include a multiturn unit capable of operating on diaphragm and gate valves up to 4”.

Paladon Systems is pleased to announce that is ready to ship the first batch of Actuators for HOCKI Project, in Mexico.

The challenge with fail-safe processes within air reservoirs can be boiled down to the lack of standardization that results in complicated and costly assemblies.

What do successful organizations, large and small, have in common? When they are confronted with required changes to their operating systems, based on new governmental regulations, they have little recourse other than to find a solution.

Cowan Dynamics, a leading industrial valve actuator manufacturer, continues to advance valve automation with the release of the E2H-ESD.

The Nuclear Power industry is extending the operating lifespan of its reactors. Originally, reactor lifespan was planned for 40 to 60 years and is now extended to 60 to 80 years. This life extension requires regulatory approval and verification that safety-related components can meet their new service (qualified) life objectives.

This article discusses a technology approach of design & development of Knife Gate Valves consistent to the AWWA C-520 industry standard. It also describes AWWA C-520 testing requirements and an approach to qualification that goes well beyond.

It is human nature that what does not trouble one, should not worry one. But, it is critical to think about how many times during field operations we evaluate or examine functionality of valves. Precautions can be made for field maintenance of valves in special cases.

Any engineer or maintenance manager must consider a litany of valve choices for placement in their various processes. For example, critical service valves are not limited to high pressure and high temperature environments.
