02 First Stage Regulators
The first stage regulator is used to reduce the inlet pressure, coming from cylinders, bulk tanks or vaporizers (normally between 6Bar and 7Bar) to a medium pressure (normally between 0.5Bar and 1.2Bar) suitable to supply a second stage regulator.
First Stage regulation is best used for installations with long pipe runs and also were a two stage regulation system provides more constant and reliable outlet pressures at the appliances, some of which are extremely sensitive to the inlet pressures provided to them.
