Application of Pressure Regulators
Pressure regulators are mainly used where only one point of use has to be supplied with gas and the cylinder can be placed right next to it.
The regulator can be directly connected to a cylinder valve. The adjusting screw of the pressure regulator allows adjustments for any desired working pressure. All regulators are equipped with relief valves to protect the connected equipment and two pressure gauges indicating the cylinder and outlet pressure.
Depending on the level and required stability of the working pressure, one or two stage regulators are used. When using a single stage regulator, the working pressure may increase with decreasing cylinder pressure and has to be adjusted by hand while emptying the cylinder. At low working pressures and high requirements on the stability of the working pressure, regulators with dual-stage or with compensated main valve have to be used.
