Unfortunately, water can really throw a wrench in the works since freezing water can plug up the inlet so no gas flows or even keep a regulator from shutting off completely. Don't you wish someone would make a product that would last your life time, but what would they do with their spare time, think of another way to rip us off. It is something to do with the reaction of oxygen on the diaphragm after prolonged exposure to nothing but propane vapour that breaks them down. Users should consult the manufacturer for specific procedures on how to check for external and internal leakage as well as the recommended frequency of the tests. David Gailey is the manager for Specialty Products for The Harris Products Group, A Lincoln Electric Co. What is the process for this? Downstream or delivery pressure will continue to climb until the safety relief mechanism on the regulator is activated (usually a relief valve or a diaphragm burst hole). This is generally a greater problem for metal diaphragms than for elastomeric diaphragms. sounds like someone didnt know what they were doing when designing the gas system or they would have tried to use as few regulators as possible unless it was retrofitted with another appliance that needs a large amount of gas… Compressed gas regulators, when not performing optimally, can lead to many hazardous situations, such as the leakage of toxic, pyrophoric or asphyxiant gases into the atmosphere, or even the risk of explosions or fire. The gas is the biggest culprit as it literally starts to eat away at the regulator. Order online or call us to s Users should closely adhere to these guidelines to protect their equipment and themselves against the hazards regulator failures can produce. Light the grill using your normal lighting procedures If the regulator was stuck, it should have been reset using these steps. Many applications require that regulators function outside; exposed to rain, snow, ice and high humidity/salinity. Turn the gas on slowly on the propane tank 9. Leakage from the diaphragm can occur if it has exceeded its normal life. How long should a regulator function properly under severe conditions? These are conditions that can reduce the service life of regulator components. No not unusual at all ! The scenarios go something like this, (1) “I keep getting a lock-out in the heating section of the roof top unit.I have 24 VAC to the valve and it won’t open. As I mentioned, the regulator brings gas to your grill burners. Users should consult the manufacturer for specific procedures on how to check for external and internal leakage as well as the recommended frequency of the tests. Now that your grill is ready, make sure to avoid these common burger faux pas. This is how you do it on a BBQ grille. The gas will then be at the lowered pressure which will pass through the series of regulators without any resistance at all. This is all about propane hose adapters, hoses with regulators, regulators, and gauges you can use to either replace or improve your propane gas grill. LPG as… The standards for typical regulation is that natural gas will run through the main gas line at 110 psi which means 10 pounds of pressure per square inch. Usually they either work or they don't. This will insure that the performance of the device is being checked at regular intervals where problems can be easily addressed. Most pressure adjusting springs are also made of steel which, even though they are inside the regulator, will corrode over time in a humid environment. An over-fill protection device valve is a mandatory component in all propane tanks. In the market for a new regulator? The second and perhaps the most common type of regulator failure is the internal leak, sometimes called creep or crawl. When the gas line splits off the main to run up into someones property there is a regulator after the meter that steps the pressure down to 2 psi. Most of the applications that Stromquist & Company provides natural gas pressure regulators for are commerical or industrial projects, but the principals apply for most residential and appliance as well as Lp or natural gas pressure regulators. How do you think about the answers? Shut off the valve on the gas tank and remove the regulator and hose from the tank. 0 out of 5 (0) GECA REGULATOR 3/4 SET 2.75KPA. This is done so that there is room for your propane to change back to gaseous form, so it can be used. It has spark from the ignitor but I can't get gas up to the top. Over a period of time (normally years) these materials tend to become brittle and/or crack. These are questions that manufacturers are constantly asked by consumers concerning the life expectancy of compressed gas regulators. To insure that the gas service will not adversely affect the expected life of a regulator, contact the manufacturer to discuss the application as well as the regulator’s metallic and non-metallic materials of construction. Long Regulator Life Starts With Good Maintenance. When pressurized natural gas enters the natural gas regulator, it will push up against the diaphragm, bringing tension to the spring. When you hook up the regulator to the tank, there is flow through the regulator … Turn off the grill, the side burner and the LP gas tank. The diaphragm will move upward as far as the tension of the spring will allow it to go. Because of the salty air and harsh environment in and around an oilrig, this regulator may need a major overhaul or replacing in as little as three months. Line Regulators are single stage regulators that are used to provide point-of-use pressure monitoring and control. Those are a lot more expensive and are typically a lot better built and very precise in their outlet pressures. Usually they either work or they don't. Regulators should also be tagged or labeled to identify the last date of inspection. Make sure the gas supply is off before you do this. A can of air can also do the trick if the tapping isn't working. At individual natural gas appliances the gas pressure will be regulated to about 0.25 psi ; Gas Regulator Pressure & Flow Test Procedures Question: How do I check the gas coming out of my regulator for LP ? ? When you compress Propane it condenses into a liquid which makes it much easier to store in a tank than natural gas, which does not easily compress. Gas Pressure Regulator, GASLAND 1/2" NPT In/Out Gas Pipe, 1/2 PSI(3.5 kPa) Gas Inlet LPG10"WC. We're the largest distributor of Elster Gas Regulators in the United States. LPG stands for Liquefied petroleum gas. Will an indoor/outdoor extension cord work as a pipe wrap to thaw ice in pipes? How to Know If a Propane Gas Regulator Is Working Properly. Elastomers. Here are six things you need for sizing a natural gas regulator: gas type, inlet pressure, outlet pressure, flow, pipe size, and location. Both of these companies boast a 30 year service life for their regulators. LPG includes mixes that are primarily propane (C3H8), primarily butane (C4H10) and, most commonly, mixes of both propane and butane. Here are the basic parts that make up Maxitrol gas pressure regulator and really pretty much any gas pressure regulator. We need to soften the water in my house. Diaphragms crack and there you go. Natural gas is most troublesome because it cools the most and is most likely to contain moisture. –If your burners light up unevenly, for example, the burner on the far right flickers or hardly lights, the middle burner has low flame, and the left burner has … There are three main parts: the loading mechanism, sensor element and control devise, which all work to control the amount of pressure of the gas. ? I kid u not, I've seen them last as little as a few months, and as long as 10-15 years (with proper cleaning of course). So as you can see the Maxitrol RV 131 will go up to a four inch flange and the Maxitrol RV 52 get you down to the half and three quarter inch straight through gas pressure regulators. Many industrial regulators have elastomeric components such as reinforced neoprene diaphragms, viton seals or seats, nitrile o-rings, etc. Manufacturers as well as users who operate regulators in a critical service application, should consider these issues when recommending or purchasing pressure regulators. Natural Gas pressures: Natural gas in the natural gas service line in the street will be found at pressures from 60 psi down to as low as 0.25 psi. 1813C, 1813B, and 1803s all IN STOCK! They are a cheaply built device that is not required to produce precise output pressures. He has been with Harris for 27 years and served as past chairman of the CGA Industrial Gas Apparatus Committee. It is unusual, but not uncommon. Air too can cause freezing if not very dry. Unfortunately, the answers are varied and somewhat complicated. In Photo 1, the gas from the gas main enters the meter and regulators at the “service valve” at a pressure of 50 to 75 pounds per square inch (psi) (3.515-5.273 kg/cm 2) or higher. Leakage can also occur if port threads have been damaged due to changing connections. According to the Compressed Gas Association Pamphlet E-4, diaphragms must have a minimum life of 25,000 cycles if made from an elastomer and 10,000 cycles if made from a metallic material (usually stainless steel). The propane gas regulator is one of the most important parts of a propane gas system. Failure of internal components generally results in leakage of the regulated gas to the atmosphere. Also, make sure some precaution, and follow our tips to avoid gas grill regulator problems. Still have questions?
