Every regulator comes with a 10, cycle assurance. CONCOA has a long history of providing solutions to challenging gas control applications for the analytical, research and scientific markets.

CONCOA invests substantially more in research and development than the industry average in order to develop a continuous stream of new products, here is one typical example:. The inert amorphous silicon coating ensures superior stability and greater calibration accuracy than the bare L stainless steel and is ideally suited to meet new regulations for low level sulphur analysis.

While all regulators can reduce pressure in a gas system, CONCOA high purity regulators conform to very exacting standards of pressure control. Below, we discuss some bases of comparison that can help you navigate this catalogue and choose a regulator that regulaator suits your needs.

Of course, our Customer Service representatives would be happy to answer any further questions you may have about regulator design and operation. Single stage regulators reduce pressure in a single step to deliver a pressure within a specific range. Regulators designed in this way will show a slight variation in delivery pressure as the cylinder pressure falls during use. For this reason, single stage regulators are best suited for applications where a constant outlet pressure is not critical, where an operator can monitor and readjust pressure, or where inlet pressure is constant.

Dual stage regulators perform the same function as single stage regulators. However, delivery pressure remains constant as cylinder pressure decreases, and greater accuracy in pressure control is maintained because the pressure reduction is performed in two steps. Dual stage regulators are recommended for applications requiring a constant outlet pressure over the cocnoa of a gas cylinder. Helium leak integrity is a measurement of how well a fegulator prevents gases from leaking into or out of a regulator body.

In this case, a Helium Leak integrity rating of 1 x would indicate that the regulator would leak enough gas to fill one cubic centimeter every 33 years.

If the rating were 1 xthe regulator would leak enough gas to fill one cubic centimeter in just 17 minutes. Helium is used as the test gas because it is chemically inert, it is easy to detect, and it is an extremely small molecule with the ability to pass through the smallest leak. The lower the helium leak specification, the better the regulator will be at preventing leaks into the atmosphere and at minimizing contamination from gases outside the body.

The materials of construction for a regulator should be selected based on the properties and purity of the gas being used. Brass is compatible with most of the non-reactive gases. A choice of forged body or barstock construction is available. Forged body regulators are economical; however, their internal surface finishes are relatively rough as compared to barstock body regulators.

Barstock body regulators have all wetted surfaces machined to a smooth finish, which reduces the possibility of contamination. Aluminum is an economical lightweight alternative to stainless steel for many of the mildly corrosive gases. Refer to the compatibility charts on pages or consult your gas supplier to determine suitable materials of construction. Refer to CGA publication V-1 for more information. Please note that a CGA connection limits the temperature range of a regulator to the guidelines of the connection.

The flow charts found on pages are a graphical representation of test results which show the change in outlet pressure. To use the regulstor, determine the maximum no-flow pressure permitted by your system. Locate this pressure on the vertical axis of the chart. If there is no curve for your specific condition, interpolate a curve. Follow the curve to the desired flow rate on the horizontal scale. Read horizontally to the left to determine the corresponding pressure drop.

The diaphragm is a regualtor element crucial to the function of the regulator and the purity of gas delivery.

Stainless steel diaphragms are corrosion resistant and have low leakage rate characteristics. Neoprene diaphragms may offer more sensitive pressure control, but do not offer the gas purity of stainless steel.

While a single or dual stage regulator of the appropriate material will suffice in most gas services, some applications require specially designed regulators. For example, in the Series, the Series regulators are specifically designed for use with highly corrosive gases, and the Series regulators can safely deliver gas at extremely high pressures.

To meet the rigorous requirements of end-users in the analytical, scientific and electronics markets. CONCOA has developed a unique regulator seat assembly that incorporates the numerous individual parts of a standard regulator seat into a single component.

The result is longer life and reliable performance. This smooth transition from high pressure to low pressure reduces the effects of gas surge on the diaphragm and minimizes regulator hum. In addition, the lateral flow passages induce a swirling effect which yields a completely swept internal cavity for complete purging. PTFE is an inert material which will not react with or contaminate any high purity gas.

In addition, PTFE retains its sealing properties over a wider temperature range than other seat materials. High Load Marginal Spring — The purpose of the marginal spring is to close the seat independently of gas pressures. In addition, this filter is very regulagor and its large surface area is resistant to clogging which allows unrestricted flow.
