Here you can find an excellent introductory video series on electric valve actuation. The series begins with the basics and explores operation, technology, control, monitoring, and diagnostics.

Here’s a brief 1:40 YouTube video, Treating control valve noise with Fisher Whisper technology, that shares how the bar continues to be raised for control valve noise reduction by reducing sound pressure levels to a manageable level with Fisher Whisper technology. More innovations to come!

This article discusses a recently introduced PRV design that replaces bellows with a balanced diaphragm. This new balancing technology can be installed as an upgrade to standard bellows PRVs, and it extends backpressure limits while providing greater flow capacity than a similarly sized balanced bellows PRV.
