Madas supplier in Romania
Safety valves and control equipment for gas
Headquarters: San Pietro di Legnago, Italy
Who is Madas and what does it make?
Madas is an Italian manufacturer of safety and control valves for gas, headquartered in San Pietro di Legnago, in the province of Verona. The range covers normally closed and normally open solenoid valves for gas, overpressure and underpressure shut-off valves (OPSO/UPSO), safety and relief valves, gas pressure regulators, gas and liquid fuel filters, shut-off valves for fuel and complete gas trains. For the Romanian market we can quote individual components from these families, for boiler houses and industrial gas installations.
The Madas range covers the safety chain of a gas installation — from the automatic shut-off valve on overpressure or underpressure, through the pressure regulator, to the gas filter that protects the rest of the installation from impurities. Pressure regulators are split into ranges by inlet pressure, from low-pressure installations (P1 maximum 2 bar) to ranges with inlet pressure of up to 5 bar, and the safety valves are available with connections from 1/4 inch (DN 8) to 6 inch (DN 150).
For installers in Romania, Madas makes sense for industrial boiler plants, gas burners and pressure regulating and metering stations, where safety rules require automatic shut-off of the gas supply in case of overpressure, underpressure or excess temperature.
What do we supply from the Madas range?
| Product | Description |
|---|---|
| Overpressure and Underpressure Shut-Off Valves (OPSO/UPSO) | Valves that automatically shut off the gas supply when an overpressure threshold is exceeded (OPSO) or when pressure falls below a minimum threshold (UPSO), fitted on the gas line to protect the burner and the downstream installation. They are reset manually, with a jerk-handle lever, after the cause of the trip has been remedied. Connection sizes cover a wide range, from small connections for residential installations to large DN for industrial installations. |
| Gas Pressure Regulators | Gas pressure regulators, split into ranges by inlet pressure — variants for inlet pressure of up to 2 bar and variants for ranges from 0.5 to 5 bar. They keep the outlet pressure to the burner or consuming equipment constant, regardless of pressure variations in the supply network. |
| Gas Filters and Self-Cleaning Liquid Fuel Filters | Gas filters fitted upstream of the regulator or burner, to retain impurities from the distribution network, alongside self-cleaning filters for liquid fuel (gas oil, fuel oil), used in continuously operating installations where frequent clogging would stop combustion. |
| Gas Trains and Fuel Shut-Off Valves | Complete valve assemblies for gas supply to industrial burners (gas trains), integrating a shut-off valve, regulator, filter and, where applicable, a relief valve in a single assembly. The range also includes shut-off valves for liquid fuel with thermal tripping at 98°C or 110°C, for automatic shut-off of the supply in case of fire. |
Why Madas?
- Safety range for the gas installation: OPSO/UPSO valves, relief valves and filters.
- Pressure regulators in several ranges, from low-pressure installations to ranges of up to 5 bar at the inlet.
- Complete gas trains, useful when upgrading industrial boiler plants.
- Shut-off valves for liquid fuel with a temperature threshold of 98°C or 110°C, for fire protection.

How do we supply Madas in Romania?
We work with Madas on the basis of the manufacturer's technical documentation — availability and lead time are confirmed in the quotation. We bring safety valves, pressure regulators, filters and gas trains in to order, through EU supply channels, typically within 1–4 weeks, depending on the reference. For a quotation we need the type of gas or fuel, the working pressure, the connection diameter (DN or inch) and, where applicable, the code of the existing component being replaced. Components are supplied to order, and availability is confirmed for each reference.
Approval of a complete gas installation configuration is established on the basis of the opinion of a licensed gas designer.
Frequently asked questions about Madas
What products does Madas deal with?
Madas makes safety and control valves for gas installations — overpressure and underpressure shut-off valves, pressure regulators, gas and liquid fuel filters, and complete gas trains for industrial burners.
How do I choose a suitable Madas pressure regulator?
The choice depends on the inlet pressure in the gas network and on the flow rate needed at the burner or consuming equipment. Madas splits regulators into inlet pressure ranges, for example up to 2 bar or between 0.5 and 5 bar, and the connection diameter is chosen according to the flow rate.
What are Madas OPSO and UPSO valves?
OPSO automatically shuts off the gas supply when an overpressure threshold is exceeded, and UPSO does the same when pressure falls below a minimum threshold. Both protect the downstream installation and are reset manually after the cause of the trip has been remedied.
Can you supply Madas components in Romania and within what lead time?
Yes, we bring Madas valves, regulators, filters and gas trains in to order, through EU supply channels, typically within 1–4 weeks of confirmation, depending on the reference. Every component is supplied to order, with availability confirmed per reference.
How do I request a Madas quotation?
Send the Madas code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
