A person needs to consider if they need a pressure regulator or a flow regulator. All regulators of high pressure are designed for accepting incoming pressure making it a regulator of high- pressure. A person should know what they need on the outlet of a regulator to know what the regulator needs. Once a person makes a determination of this, they will be in the best position to go.
A person should take into consideration the flow rate of the outlet or the requirement of pressure. Given flow rates or pressures can be needed for a given instrument. Making determinations of the needed levels will allow a person to choose a regulator with a correct outlet requirement or a range that is via le that includes the value needed.
Most regulators have given flow rates that are fixed, while there are others that have a flow rate that needs selection. A flow regulator that is continuous will offer the needed flow rate by an instrument. In a case where the analyzer has an internal pump then a flow regulator on demand will offer the flow once a vacuum is placed on the regulator. Pressure regulators have outlets of different ranges. A person should choose a range that will match what is required.
Gas type and concentration should be taken into consideration by a person. The gas mixture will be determined by the material needed of the regulator. It is also vital when selecting other materials like tubing. Gasses that are highly corrosive like hydrogen cyanide need stainless steel regulators. Mixtures that are non corrosive will need brass. It is essential for a person not to utilize nickel plated brass for concentrations that are high.
It is good and advisable for a person to choose a stainless gas regulator specifically because of its high corrosion resistance ability. It is the material that is more favorable in different environments. Before settling on purchasing a high pressure regulator, choosing the material should be key.
A person should know the inlet connector needed. The inlet connector on the regulator needs to match the valve of the gas cylinder. A person needs to determine what form of valve is on the cylinder , if it is a new or old cylinder. The material used in the valve and regulator will be determined by the type of the gas.
An individual should make determinations if they need a single or a dual stage regulator. The pressure of an outlet of a specialty gas regulator has a relationship that is inverse to the volume of gas in the cylinder. As the volume of the gas reduced, the outlet pressure will increase.
A person should determine the type of outlet connection that they need. Many flow regulators have a hose barb connection for tubing of low pressure. Many various outlet connectors are available for a person in the market for their gas distribution system. A person should make a choice of a connector that will satisfy the requirements.
