Madas Pressure Regulator Valves RG Series

Product Details

Energy Combustion, Ahmedabad importer and suppliers of MADAS brand Gas Pressure Regualator and all other components. Madas is an Italian manufacturer known for high-precision gas pressure regulators used in industrial, commercial, and domestic gas systems (Natural Gas, LPG, Biogas). Their regulators are designed to provide a constant downstream pressure regardless of inlet fluctuations. Below is a breakdown of the primary models and their technical specifications. 1. Popular Madas Models Madas uses a specific coding system to differentiate features like safety shut-offs and built-in filters. Series Description Key Features RG/2MC Basic Regulator Standard pressure regulator without filter or safety shut-offs. FRG/2MC Filter-Regulator Includes a built-in filter (FRG = Filter + Regulator). RG/2MB Safety Regulator Includes OPSO (Overpressure Shut-Off) as standard. FRG/2MB Filter-Safety Regulator Includes Filter + OPSO + UPSO (Underpressure Shut-Off). RG/2MCS High-Capacity Designed for larger flow rates and industrial burner applications. 2. General Technical Specifications Specifications vary by the specific "DN" (Diameter Nominal) size, but general ranges include: Inlet Pressure (P_1): * Low Pressure: Up to 500 mbar. Medium/High Pressure: Up to 5 bar (some models up to 6 bar). Outlet Pressure (P2): Typically adjustable from 10 mbar to 500 mbar (depending on the spring installed). Size Range: From 1/2" (DN 15) up to 6" (DN 150) flanged. Operating Temperature: -20°C to +60°C. Safety Devices: OPSO: Trips and stops gas flow if outlet pressure is too high. UPSO: Trips if outlet pressure drops too low (often due to supply failure). Relief Valve: Vents small amounts of gas to prevent nuisance tripping. Materials: Body typically made of Die-cast Aluminum; internal parts in stainless steel, brass, and NBR rubber. 3. Specific Model ExamplesFRG/2MB (Compact Series) Sizes: DN 15, DN 20, DN 25 ($1/2"$ to $1"$). Max Inlet: $5$ bar. Common Use: Individual burners or small boiler rooms. Filter: $50\mu$m filtering element included. RG/2MBZ (Large Series) Sizes: DN 32 to DN 100 ($1\ 1/4"$ to $4"$). Connection: Threaded or Flanged (PN16). Max Inlet: $5$ bar. Accuracy: AC 10 (±10% of the set pressure). Quick Reference: Safety Terms OPSO: Over Pressure Shut Off (Mandatory in many industrial setups). UPSO: Under Pressure Shut Off. Compensated Obturator: A design feature that ensures the outlet pressure stays stable even if the inlet pressure jumps or drops suddenly.
