Scope of Manual The standard gas Pressure devices ( regulators and safety shut-off devices) are those used in the assemblies dealt with This manual provides instructions for installation, startup, into EN 12186 and EN 12279 and their use has to be under maintenance and spare parts ordering for the M Series the provisions into ENs 12186 & 12279. spring loaded regulators . In the Pressure regulators manufactured by Emerson Process Management shall be used additional Pressure Product Description accessories ( slam-shut controller) manufactured and labeled by Emerson Process Management. The M Series regulators are fail open, differential strength, spring loaded whit counterbalanced shutter. They can be provided with Emerson Process Management will be not responsible slam-shut controller for minimum Pressure , maximum Pressure for any possible inefficiency due to installation of not own or minimum and maximum downstream Pressure .

3 Production additional Pressure accessories ( slam-shut controller). The regulators of the M Series due to their operating specifications are mainly used in those system where When Pressure containing parts of possible built-in safety sudden capacity variations are required, or else, where the shut-off device (SSD) valve and pilot have different cut-off of the gas distribution is controlled by solenoid valve, maximum allowable pressures, the SSD is differential such as for the feeding of burners. strength type.
