Pressure regulators, more commonly known as pressure-reducing valves, keep the output pressure constant in compressed-air systems no matter how the input pressure or output flow changes. They contain ...

[Editor’s note: This is the second in a three-part series on one of the newest refrigeration technologies: the electric suction line regulator. The first part appeared in the Jan. 12 issue of The NEWS ...

The line provides a high level of regulation accuracy and repeatability. Rather than range springs, the regulators and relays use a stainless-steel capsule as a sensing device. Its multistage design ...

Installing a recycle valve in parallel with the antisurge valve of a turbine-driven multistage (low pressure/high pressure) centrifugal compressor, in combination with control system modifications, ...
