Preset Pressure Regulator
These regulators are having preset outlet pressure. However the outlet pressure can be slightly adjusted by rotating the spring adjusted screw. The Industrial Pressure Regulator R-4109 is available with four different types of outlet pressures. These are the suitable for canteen, restaurants & small industrial furnaces. R-4110/R-4301 are low-pressure medium flow pressure regulators, mainly used for industrial furnaces and other gas appliances. R-4202 regulator is mainly suitable for Natural Gas.

Preset Pressure Regulator (Fixed Inlet Pressure)

These regulators are low-pressure high flow precision control pressure regulators and are mainly used as second stage pressure regulators.These are also used in medium size to bigger size furnaces. These regulators control the outlet pressure very precisely.
