  • 0.03 to 0.58 flow coefficient

Flow Rate Performance

The Neon Regulator Series 10 and 15 are available with a range of flow coefficients to suit different application requirements. The charts below illustrate the flow rates for regulators with 0.07 and 0.24 flow coefficients at different inlet and outlet pressures:

0.07 Flow Coefficient

Outlet Pressure (psig)Air Flow Rate (l/min) at 500 psig InletAir Flow Rate (l/min) at 1000 psig InletAir Flow Rate (l/min) at 2000 psig Inlet

0.24 Flow Coefficient

Outlet Pressure (psig)Air Flow Rate (l/min) at 500 psig InletAir Flow Rate (l/min) at 1000 psig InletAir Flow Rate (l/min) at 2000 psig Inlet

As shown, the Neon Regulator Series 10 and 15 can provide precise flow control across a wide range of inlet and outlet pressures. The flow coefficient can be optimized for specific gas delivery requirements.

Pressure Control Performance

The supply pressure has minimal impact on outlet pressure control. For example, with a 0.07 flow coefficient regulator, the outlet pressure only varies by 1.39% when supply pressure is reduced from 2000 psig to 500 psig.

With a higher 0.24 flow coefficient, the outlet pressure variation is only 2.06% over the same supply pressure range. This demonstrates the excellent regulation provided by the Series 10 and 15.

Case Uses

Medical Gas Systems

The Neon Regulator Series 10 and 15 are well-suited for handling pure medical gases like oxygen, nitrogen, carbon dioxide, and nitrous oxide. Their high purity design prevents contamination. They can provide accurate pressure control for hospital gas manifolds, dental equipment, anesthesia machines, and other medical applications.

Fuel Gas Regulation

The Neon Regulator Series 10 and 15 regulators are optimal for hydrocarbon fuel gases such as propane, natural gas, and acetylene. Their tight internal leak control and variety of seat materials allow both high pressure inlet gas and accurate low pressure outlet regulation. They are used for torch and welding gases, RV appliances, barbecue grills, and calibration gases.

Specialty Industrial Gases

The regulators can handle toxic, corrosive, and reactive gases used in industries like petrochemical processing, electronics manufacturing, food and beverage, aerospace, and more. Some examples are ammonia, hydrogen sulfide, silane, germane, arsine, phosphine, and other specialty electronic/chemical gases.

High Purity Gas Systems

Their minimal internal volume and high purity materials make the Series 10 and 15 well suited for ultra high purity (UHP) gas delivery. This includes gases like nitrogen, argon, helium, and hydrogen in analytic instrumentation, gas chromatography, ICP-MS, and other critical laboratory and process applications.

Liquids and Cryogens

With the addition of a liquid specific inlet filter, the regulators can also accurately control the outlet pressure of pressurized cryogenic liquids. This includes liquid argon, nitrogen, CO2, and inert liquified gases requiring low pressure regulation and vaporization.

The versatility and customizable construction of the Series 10 and 15 allow them to suit a wide variety of critical gas and liquid regulation applications across many industries.


The Neon Regulator Series 10 and 15 are versatile, high quality single-stage regulators designed for precise pressure control across a broad range of specialty gas applications.

With choices in flow capacity, materials, pressure rating, and connections, they can be customized to suit your specific requirements. The compact and lightweight design provides efficient gas regulation without taking up valuable space.
