Sounds of Silence – Pulse Period and Duration

Today we are, again, going to bring ultrasonic sounds into the realm of human audibility by lowering the frequency to ones that most people with normal hearing can hear.  Several preceding blogs have discussed the effects of varying the pulse width and pulse period of an ultrasonic generator in an ultrasonic cleaning system.  If you’ve …

Valves – Backpressure Regulating Valves

Pressure regulating valves were discussed in the preceding blog Valves – Pressure Reducing Valves.  Pressure reducing valves, although commonly used where pressure is an issue, are not always the best alternative.  The pressure reducing valve has a close cousin called a “Back Pressure Regulating Valve” which monitors and controls pressure in a similar but different …

Valves – Pressure Reducing Valves

It is not an uncommon practice to use flow restricting valves in an effort to reduce and/or control pressure in even the most sophisticated industrial cleaning machines.  In the blog “Reducing Flow vs. Reducing Pressure – Which is it?” the risks of using flow restricting valves to control pressure were discussed in some detail.  Reliable pressure control …
