Guias de selecção de válvulas
Orientação técnica prática sobre a selecção, dimensionamento e especificação de válvulas industriais para água para projectos de infraestrutura hídrica europeus.
How to Select and Size a Pressure Reducing Valve
Inlet pressure, flow rate and cavitation risk determine the correct PRV specification. Get these wrong and the valve will fail prematurely or provide no useful pressure control.
Butterfly Valve Selection: Body Style, Disc Geometry and Seat Material
Butterfly valves suit the majority of water isolation duties, but body style, seat material and disc geometry all affect whether a given valve is right for a specific application.
Selecting Non-Slam Check Valves for Pump Rising Mains
Spring-loaded and nozzle-type non-slam check valves prevent reverse flow slam on pump mains. Selecting the right geometry by diameter and system head makes the difference between surge protection and unnecessary headloss penalty.
Air Release Valve Selection: Types, Sizing and Placement
The wrong type of air valve in the wrong location will cause more problems than no valve at all. Understanding kinetic, automatic and combination designs prevents the most common installation errors.
RSV Gate Valve Selection: Operator Types and Installation Requirements
Resilient seated gate valves are straightforward to specify once the operating conditions, installation depth and actuation requirements are established. Choosing the wrong operator for the installation leads to valves that cannot be operated safely.
Automatic Control Valve Functions: Selecting the Right Pilot Configuration
One valve body delivers pressure reduction, flow control, level control, pump control and on-off shutoff depending on which pilot circuit is fitted. Understanding how pilots work is the key to specifying and commissioning these valves correctly.
