Many small engine manufacturers use exhaust backpressure specifications for emission conformance guidelines. Such specifications are often given to a muffler manufacturer for use in designing an exhau

Can anyone explain the usage of the adjustable port valves? By adjusting the port size, we can change the valve capacity, right? To restrict the flow (when fully open) to a very low level, do we need

I need to design several coils for electromagnetic actuators for small nitrogen valves. One is a iron-core electromagnet, another is an air coil for a moving-magnet style "voice coil motor". Both ar

In our R&D test facilities we require water at very low flowrates (10 - 300 kg/h) and high pressure (50barg) for a series of experiments. We plan to use a CAT piston pump with VSD. However we still ca

we are about to install altitude valve between 2 water tanks the 1st tank is 250 m (elev) and the other one is 90m elev. the valve will be for the lower one , the distance between them is about 2km a

I'm designing a product that has a need for an inexpensive low pressure (

Which companies make large diameter (eg 500 mm) flow control valves for water transmission mains, which can be driven by an electric actuator ?

No power since 8am now 3:30pm PoCo thinks they'll have it back on by tomorrow at 3pm. So it's on to the generator for keeping the business running. Never mind we're in the middle of a town of 50k an
