Is there a difference between LP and natural gas regulators?

Propane regulators and natural gas regulators are not interchangeable, though they both operate in the same fashion. A natural gas regulator is comprised of five components: set screw, spring, rod, diaphragm and valve.

Are all pressure regulators the same?

Are All Gas Grill Regulators the Same? Every propane gas grill uses an LP regulator, but not all regulators are created equal. Though the purpose is the same, different types of setups require different types of regulators. The type of regulator a grill needs is based on the specific propane application requirements.

Are propane and LPG regulators the same?

Please note that Propane gas cylinders contain considerably greater pressure than Butane cylinders and as a result, regulators are designed for use with either Propane or Butane and are not interchangeable because of their different design pressures and the different connections on the cylinder itself.

Can I use any gas regulator?

Each regulator is designed to fit a specific type of cylinder valve and a regulator that fits one type of valve will not fit any of the others. The valve on Propane cylinders has a screw thread and only accommodates Propane regulators.

How many PSI is a gas grill regulator?

How many PSI is a BBQ regulator? Generally, propane pressure should be between 100 and 200 psi ensures that the liquid propane gas remains in a liquid state.

Are Calor Gas and flogas propane regulators the same?

A. Both Calor and FLOGAS clip-on regulators are low-pressure 21mm. and fully interchangeable.

What regulator do I need for propane?

For your propane tank with fill valve, you most likely need the Camco Horizontal 2-Stage Propane Regulator w/ P.O.L – 160,000 Btu/Hr # CAM59333. This will have the 1/4 inch NPt inlet and the 3/8 NPT outlet and will maintain a constant 11 inch water column propane pressure for your vent-less heater.

Can you use butane instead of propane?

Can I switch from Butane to Propane? … Propane operates at a higher pressure than Butane so it is not possible to use a butane regulator on a propane cylinder and vice versa.

Pressure Regulators – Design Principles, Types and applications

A pressure regulator is a device which controls the pressure of liquids or gases (medium) by reducing a high input pressure to a controlled lower output pressure. They also work to maintain a constant output pressure even when there are fluctuations in the inlet pressure.

Pressure regulators, in various forms, are used in many domestic and industrial applications, like regulating propane used in gas grills, to regulate oxygen in healthcare equipment, to supply compressed air in industrial applications, to regulate fuel in automotive engines and aerospace applications. The main aspect that is common across all these applications is pressure control – from a higher source pressure to a lower output pressure.

Spring loaded poppet valves are commonly used as a pressure reducing element. Poppet valves have elastomeric sealing in regular applications and a thermoplastic sealing in high pressure applications. This seals the valve seating against any gas or fluid leakage. The poppet valve is controlled by the spring force to open the valve and let the medium flow from inlet to outlet. As there is a rise in output pressure, the poppet valve closes due to the force generated by the sensing element, which overcomes the spring force.

Pistons are normally used for high pressures, rugged applications and applications where wider tolerances on the outlet pressure are acceptable. They tend to be sluggish due to friction between the pinion sealing and regulator body.

For higher accuracy, a diaphragm type of sensing element is suitable. They are made of elastomer or a thin disc type of material which is sensitive to changes in pressure. Diaphragms tend to have lower friction than piston type designs. They also provide a higher sensing area, for a given regulator size.

Pressure and Gas Type

The two LPGes, Butane and Propane, are very similar, and consequently many domestic appliances (e.g. most domestic cookers) are designed to run on either gas, but the standard supply pressure is somewhat different for each gas to accommodate the differences in the characteristics of the two gases. In the case of Butane, the standard supply pressure is 28 mbar (11" water gauge) and for Propane it is 37 mbar (14" water gauge) - regulators that supply either of these pressures are called "low pressure regulators". The appliance itself will have a badge on it identifying what gas and what pressure it is designed for. There are some appliances (not many) designed to work on considerably higher pressures and these use "high pressure regulators", and again these are clearly marked with what gas and what pressure they are designed for.

Each regulator is designed to fit a specific type of cylinder valve and a regulator that fits one type of valve will not fit any of the others. The valve on Propane cylinders has a screw thread and only accommodates Propane regulators.

Butane is supplied by Flogas under two brands, Flogas and Ergas. The Flogas Butane cylinders are yellow and always use a "Jumbo" valve. There are two types of Ergas Butane cylinders: the orange ones have the same "Jumbo" valve as the Flogas cylinders, but the blue/green cylinders have a much narrower "Compact" valve.

High-pressure regulators have a much narrower nozzle than that fitted to low-pressure regulators and use a much narrower hose (see picture below).
