A trend has been gaining steam: Electric, modulating, pressure-reducing valves (PRVs) are increasingly replacing traditional self-piloted regulators in steam systems. The adoption of this “smart” ...

The manifolds use a common air supply to provide electronic proportional control of output pressure from any combination of four, six, or eight station units through the use of a DeviceNet protocol.

Pilot pressure can be understood as the pneumatic control signal that defines the setpoint of a regulator. This pilot signal is generated by a separate pilot device in pressure control systems that ...

This article examines an urban gas network that experienced pressure fluctuations that manual regulators could not safely control. These issues were compounded by hazardous Zone 0 conditions that made ...
