The pressure regulator is used to adjust the precharge pressure between the nitrogen cylinder and the accumulator. For the operators safety, when using nitrogen gas cylinders, it is necessary to install a pressure reducer. It allows to reduce the available pressure in the cylinder, to the required pressure. The reduction is manual and directly visible on the gauge.
With this reducer, you can avoid the possibility to preload an accumulator that has a lower working pressure than the nitrogen cylinder pressure. The inlet connection is coupled directly to the nitrogen cylinder connection in the country of installation, while the preload tube it’s connected to the reducer outlet. The reducer has a strong construction and it’s suitable for nitrogen cylinders up to 200 barg.
