Ideal for BBQs, camping stoves, boiling rings, caravans, space heating and many more applications. It has two separate reset mechanisms, (a) one for locking out due to too low a pressure which is the section with the green tipped lever and (b) one for too high a pressure which is under the red cap . The lock up regulator, when there is a NO FLOW demand from the equipment, will shut off flow from the regulator to the equipment’s safety shutoff valves. We're the largest distributor of Elster Gas Regulators in the United States. used in gas grills to regulate propane, in home heating furnaces to regulate natural gas, in medical and dental equipment to regulate oxygen and anesthesia gases, in pneumatic automation systems to regulate compressed air, in engines to regulate fuel and in fuel cells to regulate hydrogen. (Yikes!) A regulator with an oversized valve, for the conditions of the intended application, will result in a greater sensitivity to fluctuating inlet pressures, and may cause excessive droop. Regulators are used for gases and liquids, and can be an integral device with a pressure setting, a restrictor and a sensor all in the one body, or consist of a separate pressure sensor, controller and flow valve. The picture shows it in the ON position. When there is a pressure drop of more than two to … Their design works well for all types of gas-fueled equipment, too.

This pressure should not exceed 100 … Gas cookers, BBQs, camping stoves, gas fires and more. /Count 0 Some LPG bulk tank systems are fitted with low and/or high pressure lockout devices usually as an integral part of one of the regulators (typically domestic central heating systems and small domestric/industrial systems). These typically lock out if the tank is allowed to go empty or if they detect a fault on the system (the gas pressure in the pipework going above or below a preset limit). This is a golden colour, and typically located at the LPG tank or on the outside of the building where the gas supply enters the house. Notes: A. Be sure not to push the lever the whole way down or it will cut out the system. >> /Fcpdf1 11 0 R To reset the high pressure lock out (again it is very unlikely that this will have tripped and it usually indicates a more serious problem) unscrew the red cap and pull the plunger out until gas can be heard passing through downstream.

For the low pressure lockout, unscrew the cap (in the left-hand circle on the previous picture) revealing the plunger shown on the left. With many regulators, downstream gas pressure will creep up to line gas pressure when the boiler is off. The first is a regulator lock-up test and the other is a regulator flow-pressure test. • Optional metallic mesh filter for easy change and guarantees a longer operating life of the regulator. /BaseEncoding /MacRomanEncoding >> In addition to these stock items, we can order a wide range of other makes and models.
