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.

At Linde you'll join 80,000 talented and diverse people in more than 100 countries, all working hard to make a difference in the world.

Our coatings can reduce the effects of abrasion, oxidation, corrosion, erosion, wear, and extreme heat, helping you to make the safest products possible.

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.

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.

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.

These regulators are intended for pressure control of laboratory gases with applications requiring constant delivery pressure, regardless of supply pressure.

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.

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.

Our 54 production facilities, wide variety of gas and process management programs, and delivery systems are all designed to help get you the gas you need, when and how you need it.

Our services are extensive and include cleaning, purging, drying, displacing, leak detection, hydrotesting and inspection for piping and storage tanks.

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.

We offer a number of gas injection services from full pilot projects to well stimulation, to increase the output of your oil and gas wells.

The 4" Watts 909 Series Reduced Pressure Zone Assemblies were manufactured from 1979 and are still currently in production. The 4" 909 is a cast iron bodied device. In 1989 the 909M1 replaced the original 909. The difference was the relief valve body changed for bronze to cast iron. The relief valve bottom plug was also redesigned. Many devices were not tagged with the "M1" suffix. To be sure which model you have, check the relief valve body. The 909 will be bronze and the 909M1 will be blue epoxy coated cast iron. Check valves are self contained and the relief valve is a stem type. In 2010, the LF909 was introduced to comply with the new "Lead Free" laws. All repair parts were converted to lead free in 2013. Lead free repair parts will fit both regular 909 and lead free LF909 models. All 909 models have replaceable seats and require no special tools for repair. Maintenance ManualSpecification Sheet

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.
