TOTAL VALVE SOLUTIONS
The hydraulic laws governing level control valves are often overlooked. Incorrect sizing or application, especially at high pressures, can cause early valve failure. The two main enemies of level control valves are pressure and flow. Although related, each requires a different solution. This article outlines the rules governing reservoir inflow and how to apply them correctly to prevent…
DetailsIn a boardroom in Sandton, London, or Toronto, a high-tech control valve looks like the perfect solution. It has sensors, sophisticated pilot loops, and infinite adjustability. But when that valve arrives at a remote site in the DRC or the Zambian Copperbelt, the reality is very different. In African mining, complexity is a liability. We…
DetailsFor many years, break-pressure tanks were considered the only reliable way to create a complete pressure break in a pipeline. Advances in valve technology now offer alternatives. The Ratio Pressure Reducing Valve (RPRV) is one. Each valve uses a piston designed to deliver a precise pressure-drop ratio. Compared with pilot-operated pressure-reducing valves, the RPRV has…
DetailsWedge gate valves (a.k.a gate valves) have a metal wedge which is forced against metal seats in the valve body to create a seal. These valves are robust and usually have a long service life. But, they suffer some disadvantages:- The resilient seated gate valve (RSV) was designed to overcome these problems. The gate has…
DetailsMost people imagine massive dams with long expensive approval processes when if they think about generating electricity from water. But, there is energy available in every pipeline. The kinetic energy from the flowing water can be converted into electricity. We’ve developed two water-powered generators to harness some of this energy. This is particularly useful for…
