Keep in mind that there are some valves that cannot be converted. One of these is the flame thrower valve. You can click on the link and read information on this valve.

In the aftermarket, there are some "blank" orifice options. They are called blank because there is a starter hole to allow for the specially designed gas drill bits to have a starting place. If an orifice needs replacement, there may be an aftermarket that will work. It must have the same threads in order to fit in the valve.

This piece highlights how Bermad pilot-operated pressure relief valves (model 730) function, showcasing features and applications in a way that’s accessible for both users and operators.

Often in a fixed-speed pump under low demand times, a pump can run back on its curve to a point that is underisable as the pressure rises. This creates the potential for the water to increase in temperature. In these instances, a circulating pressure relief valve is used to keep the pressure at a safe working level, and to protect the pump.

Every grill has a BTU rating that is engineered and designed by the manufacturer. This BTU rating is located on the information sticker on every gas grill and will let you know the what the manufacturer has engineered each burner to produce. Therefore, Orifices are not "universal."  They not only will have different hole sizes but, they ill also have different diameter and thread size. Not all thread patterns are created equal.

The Bermad 730 pressure reducing valve includes a number of key components that ensure high performance in pressure reducing applications.

Pressureregulator

Using a Natural Gas orifice on a Propane grill will produce an abnormally large flame due to too much gas flowing through the hole and can be extremely dangerous.

You bought a gas grill for use with a propane bottle and now you moved to a home where there is natural gas. Think you can just hook it up? The answer is no. This is because the orifice size is different. Same holds true if you purchased a natural gas grill and moved to a home where you must purchase LP bottled gas. Here we will explain what the orifice is and its function in the gas grill.

Although pressure relief valves perform a specific function, they can be provisioned and installed in a wide variety of applications. Some of the common applications include:

Pressure valve

A pressure relief valve is typically installed on a tee off a main supply pipeline. Pressure release valves are designed to open and discharge excessive pressure above the valve set point, either to atmosphere the pressure or pipe it away to a different location.

Rupture disc

Conversion kits are sometimes available through the manufacturers since they will be drilled to the BTU specification of the brand and model grill you own. Many manufacturers are moving away from allowing the grills to be converted due to liability. It is difficult to control who is doing the conversion. Since it is gas and flammable the liability can be cost prohibitive especially if someone who is a novice is performing this task and they get hurt.

In larger pipelines, there may be many components in a network that generate rapid reduction in flows. In turn, these rapid reductions in flow generate pressure spikes. Often, a pressure relief valve is installed close to the problematic components to relieve the excess pressure.

In this piece, you’ll learn why pressure relief valves are useful, find recommendations for a range of models depending on your application and objectives, and learn how to choose the...

If you need to change gas types, the grill must be converted. Changing orifice types or converting a gas grill should only be performed by licensed gas technician as it can be a potentially dangerous task. Both types of gas are flammable and should be repaired by professionals.

The orifice, in gas grill applications, regulates the flow of gas either in a Natural Gas or LP Gas (Propane) application. The spud orifice is a male fitting (see far left picture) that will screw into the valve where as the hood orifice (see far right picture) is a female fitting that will screw onto the male valve end (see far right picture). You cannot operate a gas grill without an orifice.

The orifice hole size determines the BTU rating and the gas type of the grill. The BTU rating will determine the amount of heat produced by your grill burner. Gas types are not interchangeable. Natural Gas orifices will have a larger hole as it is a lower pressure gas and Propane is a compressed gas and the orifices will have a smaller hole. They are not interchangeable. You never want to use an orifice that is drilled for Natural Gas on Propane or Propane for Natural Gas.

In critical supply pipelines with very sensitive old pipeline infrastructure, pressure reducing valves are often supplied on-line. This helps to ensure pipeline pressures operate at lower, safer working conditions. Pressure relief valves are often fitted immediately downstream of a pressure reducing valve; this relieves any excessive pressure in the event of PRV failure or a rapid decrease in supply downstream.

In any pressure reducing station, it’s critical to ensure that the downstream pressure is kept at a constant in all flow conditions, regardless of demand. Understanding the need for a...
