The brass 4094 and stainless steel 4095 Series regulators are intended for primary pressure control of non-corrosive gases at a maximum inlet pressure of 6000 psig, while the 4096 Series regulators are used at a maximum of 3000 psig.
The brass 4097 and 316 stainless steel 4098 Series regulators are primarily installed on cryogenic vaporizing systems.
The 4008 Series regulators are intended for primary pressure control of mildly corrosive high purity gases such as ammonia, hydrogen sulfide, and sulfur dioxide, or for applications requiring the compatibility of an aluminum body regulator.
The 4448 Series regulators are specifically designed for heat and vaporized media before and after pressure reduction, and are classified to meet Class 1, Groups B, C and D code requirements.
The 301 and 302 Piston-Sensed High Purity Low Flow Series Regulators can be used in applications where precise pressure control is required for low flows. These regulators can also be used for transportable cylinders.
