Elster has developed a range of safety control devices to guarantee the safe control of gas to protect equipment and appliances from excessive variations above and below the designed pressure parameters. This includes pressure and creep relief valves, over pressure and under pressure slam shut valves and low pressure cut off valves.
They can be used with natural, liquified petroleum and manufactured gases.
These units, designed where appropriate to National and International standards, give high efficiency and sensitivity with maximum flow and minimum pressure loss.
J120
The J120 is a safety valve which ensures the integrity of an installation in the event of loss of gas pressure. In the event of pressure drop, the J120 is activated and shuts off the gas supply to the downstream appliances until the manual or automatic reset mechanism is operated. The J120 is available in sizes from ¾" to 2" and supplied factory set. The J120 ensures the safety and ...

S300
The S300 in-line over pressure slam shut (OPSS) protects gas installations, especially polyethylene pipework, from dangerous overpressure conditions and can be fitted either before or after the first stage regulator (see over the page for installation diagrams). Versions are available with either internal or external impulse. When the pressure increases above a predetermined value the trigger ...
