These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. Reduce contaminants in gases used in research sample systems, emission monitoring systems, chromatography, and other high-purity applications.

There are various types of regulators, but their function is the same: to use a valve system to control natural gas or propane pressure or other gas flow. Common appliances that use regulators include gas stoves, propane grills, or oxy-fuel bottles for welding.

Emerson’s natural gas regulator valves maximize system uptime and ensure safe and accurate gas supply to equipment and customers while reducing maintenance cost and emissions.

The 400 Series regulators are for use with transportable 17 and 34-liter non-refillable cylinders using a CGA 600 valve. These single stage, piston style regulators are designed for non-corrosive service.

Double-diaphragm pressure regulators use a thin, disc-shaped sensing element that responds to changes in pressure. The diaphragms connect to a valve stem that adjusts and balances the flow rate of fluids and reduces friction and wear and tear …

Gas Regulators from Honeywell and Robertshaw offer precision control for almost any gas system. By maintaining the right pressure and flow, they allow your systems to run smoothly without any hiccups. Our Gas Regulators are designed with safety at their core.

2025年2月19日 · Gas regulators operate on the principle of pressure reduction. They typically consist of a valve that controls the gas flow, a spring-loaded diaphragm mechanism to adjust the valve, and a pressure sensor. When connected to a gas source, the regulator allows gas to flow through the valve until the set output pressure is reached.

2023年9月13日 · The inlet side of the regulator is where the gas supply enters and there is typically a valve that opens and closes by the force of a spring pushing on a diaphragm at the top of the regulator. In some regulators, such as the Pietro Fiorentini models, there …

Gas regulators attach to cylinders or pipelines and have a reducing valve that controls or regulates the pressure of gas used to operate instruments. Gases are supplied as compressed gas in high-pressure cylinders, low-pressure cryogenic cylinders, or pipeline installations.

Most standard pressure reducing regulators come with a full internal relief valve to protect the downstream equipment. Other options include indoor ventless, integral slam-shut valve and high pressure specialty regulators. Let Norgas help you select the right gas regulator for your application.

Pressure reducing regulators, also known as pressure reducing valves, are mechanical devices which achieve automated pressure control without an external power source. Pressure reducing regulators reduce a high, often variable upstream pressure to a lower steady outlet pressure despite varying flow demand from the equipment it is supplying.

Gas holding the valve closed then vents from the top of the motor valve diaphragm to atmosphere, allowing the valve to open and the upstream pressure regulated. 2.5 Stem Assembly Opening Animation The regulator will begin controlling upstream pressure as it increases or decreases, maintaining a constant back pressure set point.
