Conduit Hydropower: Recovering Energy One Control Valve at a Time

Conduit Hydro One Control Valve at a time SOARAll water distribution systems have one thing in common: It takes energy to move water from one location to another. The energy required to move the water can come from gravity or from pumps, both of which convert the water’s potential energy into kinetic energy. In a typical water distribution system, control valves are used at some point to manage this built-up energy, otherwise known as flow and pressure.

As water travels through a control valve, energy within the water is simply ‘burned off’ in the forms of noise, heat and vibration. Conduit hydropower installations aim to recover this lost energy by converting it into electricity while still regulating flow and pressure in a distribution system.


Improved Electric Actuator Reliability in Severe Service

High Vibration ModificationsAs you walk onto the switching valve deck of a coker, the first thing you notice is the heat. Cokers are used in the process of upgrading bitumen to crude oil—specifically to remove the heavier hydrocarbons from the process stream.

Non-Destructive Radiographic Inspection of Steel Castings

Non-Destructive Radiographic Inspection of Steel Castings 4Radiographic inspection technology has been used for industrial inspection for decades. While radiographic inspection of mission critical cast pumps and valves for nuclear power generation, offshore drilling and military applications has steadily increased since 1978, the growth rate started to change dramatically in 2010. Catastrophic failures at Fukushima and in the Gulf have caused many industries to revisit their exposure and recognize the impact and risk associated with product failure in the field.

To learn more about the actual process of ND radiographic inspection, VALVE Magazine spoke with Stan Truselo, quality assurance manager at Bradken’s Tacoma, WA facility.

What Lies Ahead for Institutional Construction?

Harvey BernsteinAt VMA’s annual Market Outlook event held in August 2013, Harvey Bernstein, vice president of industry insights and alliances at McGraw Hill Construction, appeared for the first time as a speaker and shared important insights into the key trends and outlook for institutional construction.

U.S. Construction Trends and Outlook

The data from which Bernstein extrapolated the industry trends came from six different sources including Dodge Construction Outlook and Forecasting Service, ENR Top Lists and the Industry Association Network.

SMRs Present Opportunities for Valve Manufacturers

Terra Power small scale reactorIn Part One of our two-part series on small modular reactors (SMRs), we introduced several projects in development, and presented a few of the situations in which SMRs could provide a reliable, economically sound solution for power production. In this final installment, we examine the challenges for these projects and the opportunities valve manufacturers could see in this sector.
