PRESSURE REGULATORS Process Management

M Regulators M/ Series Pressure Regulator Their technical and operational features make the MN/Series spring-loaded regulators the choice of preference in those applications requiring sudden changes in capacity or where gas shut-off is solenoid-controlled as with domestic or industrial burners. These regulators can be employed with natural, manufactured, propane, other gases and air so long as these are duly filtered and do not contain high percentages of benzol. Main features: • Fail Open regulator • Counterbalanced valve • Wide pressure regulation range • Full seal at zero flow • Easy...

M Regulators Operation HOW THE REGULATOR WORKS The range of position of control member depend from actuator assembly (spring-stem-diaphragm) movements. MBF-M Monitor + Shut-off The Diaphragm divides the Regulator control head into two chambers. The lower chambers is connected to regulated pressure Pd, and the other, where the spring regulator is located, is connected to atmospheric pressure. When the contrasting actions of the spring and outlet pressure coincide, the mobile diaphragm-stem-valve assembly remains motionless, and outlet pressure matches spring set point. An increase in...

M Regulators Sizing Selection should be based on maximum capacity demanded by working conditions. In the DN 25-65 MN series regulator the impulse connection is incorporated in the outlet flange. Maximum capacity in these models is limited by speed of gas flow. Capacity in these cases can be calculated as a function of actual outlet pressure as shown in the following chart. The outlet pressure capacity chart can be used for quickly checking that capacity demand falls within regulator operating range. If capacity demand is greater than regulator operating range, an expansion cone will have to...

M Regulators Slam-Shut Device The OS/66 spring loaded slam-shut devices is used with M series regulators with built-in shut-off device. Technical Features Servomotor Body Resistance (bar) OS/66, OS/66-AP Body: Aluminium Cover: Steel Diaphragm: NBR Rubber Built-in multi-path Up to 10 dB(A) attenuation

M Regulators Accessories Proximity Switch In order to send the shut-off closing signal, a proximity switch suitable for installation in hazardous area is used. The use of this switch foresees the application of an intrinsic safety separation barrier which should be installed in safe area. The distance between the proximity switch and the barrier should be calculated according to the type of gas and installation electrical specifications. The proximity switch should be positioned at about 0.5 mm from the stem (S). The adjustment is made by means of adjusting nuts Electrovalve for remote...
