Regulators

Gas Regulators: High Pressure, Cylinder, Carbon Dioxide, High Flow & More

Excelling under pressure

Most specialty gases are supplied in cylinders compressed to high pressures. Pressure regulators reduce the pressure within the cylinders to a level that can be safely used in your operating system. Proper regulator selection is critical for both the safety and effectiveness of your operating systems.

Take a look at our data sheet for more information about how to select and order regulators. View the summary and reference guide to see which regulator Series is recommended for each gas and which model best suits your needs.

Carbon Dioxide Regulators -

With single stage chrome brass barstock body, 316L stainless steel diaphragm, and electric heating, our 3008 Series regulators are specially designed to prevent freeze-up problems associated with high flows of carbon dioxide and nitrous oxide during continued use.

Carbon Dioxide Regulators

Critical Purity – 4000 Series Regulators -

These stainless steel and brass regulators are highly recommended where purity and contamination requirements are extremely important. They are most often used with critical purity gases (> 99.9995% or purity grade 5.5) and toxic or flammable gases, where vent lines are required from the regulator. The 4000 Series regulators are available for both corrosive and non-corrosive service, and come standard with a relief valve for secondary regulator protection.

Dewar Regulators -

With single stage chrome-plated machined brass body and a 316L stainless steel diaphragm, the 2006 Series regulators are intended for primary pressure control of gases supplied in cryogenic liquid cylinders.

High Flow Regulators -

With brass barstock, stainless steel bodies and 316 stainless steel diaphragms, the four-port 4083 and 4084 Series Line Regulators and six-port 4085 and 4086 Single Stage Series Regulators can be used in many different applications including high flow purging, semiconductor manufacturing, manifolds and line regulation.

High Flow Regulators

High Pressure Regulators -

The nickel-plated brass 4092 and 316 stainless steel 4093 Series regulators are intended for primary pressure control of non-corrosive gases at a maximum inlet pressure of 6000 psig.

The 145 Series special purpose piston regulator is designed for applications requiring inlet pressures up to 6,000 psi. The piston design requires little or no maintenance.

High Pressure Regulators

High Purity – 3000 Series Regulators -

These nickel -plated brass and stainless steel regulators are recommended for applications where diffusion resistance is an important factor in ensuring purity. They are most often used with high purity gases (equal to 99.999% or purity grade 5.0). The 3000 Series regulators are available for both corrosive and non-corrosive service.

High Purity 3000 Series Regulators

High Purity Economical – 2000 Series Regulators -

These chrome-plated machined brass regulators have similar features to the 3000 Series with a few specific design characteristics. They are most often used with high purity gases (> 99.999% or purity grade 5.0) when higher flow rates are required and cost is the most important issue. The 2000 Series regulators are only available for non-corrosive service.

High purity Eco2000 series regulator

Lecture Bottle Regulators -

With single stage chrome-plated brass and stainless steel barstock bodies and 316L stainless steel diaphragms, the 3025 and 3026 Series regulators are specifically designed for use with corrosive and non-corrosive gases in lecture bottles.

Lecture Bottle Regulators

Low Flow Regulators -

The 170 Series low pressure line regulators are designed to allow for lower inlet pressures and to provide sensitive and accurate pressure control of non-corrosive gases at low outlet pressures. The large rubber diaphragm delivers a steady flow at pressures below 10 psig and the 2-1/2” inch pressure gauge makes outlet pressure setting easy and accurate.

Low Flow Regulators

Purge Assemblies – 5002 Series -

The 5002 Series purges are designed for use with high purity gases to insure system integrity upon breakdown of components or during gas source changes. Most commonly, these purge assemblies are used with pressure control devices as an integral option or can be used within gas delivery systems to isolate pressure or flow control equipment.

The 5002 Series purges are offered in brass and stainless steel with diaphragm packless valves. Optional testing can be provided to certify that these purge assemblies are helium leak-tight for the most demanding services. These devices are intended for use with chemicals that are compatible with the listed materials.

Semiconductor (Corrosive) Regulators -

The 7002 and 7003 Series regulators are intended for primary or secondary pressure control of the highest purity gases or as point-of-use pressure control in semiconductor process gas distribution systems. The 7004 Series regulators are intended for primary pressure control of semiconductor process gases and applications requiring constant delivery pressure control, regardless of supply pressure variations.

Semiconductor Corrosive Regulators

Special Application Regulators -

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.
