Compact Tartarini Type FL MFL BFL Pressure Reducing Regulator Industrial Gas Pressure Regulator for Natural Gas

The Tartarini FL series is a pilot-operated pressure reducing regulator designed for accurate control of natural gas, air, and other non-corrosive gases. It features a balanced valve plug design for stable outlet pressure even with varying inlet pressure or flow demand. The FL series is widely used as the main regulator in gas distribution stations, industrial plants, and commercial metering setups where tight pressure control and high flow capacity are required.

• Pilot-operated for precise outlet pressure control
• Balanced valve plug – minimal outlet pressure variation
• High flow capacity with low droop
• Internal relief valve option (some models)
• Easy maintenance with removable pilot and valve assembly
• Wide range of outlet pressure settings
• Soft-seat design for tight shut-off

• Sizes: DN 25 to DN 150 (1" to 6")
• Inlet Pressure Range: Up to 50 bar (some models higher)
• Outlet Pressure Range: 10 mbar to 10 bar (depending on pilot spring)
• Accuracy Class: Up to AC 5 / AC 10
• Lock-up Pressure Class: SG 10 / SG 20
• Body Material: Ductile iron or steel
• Connections: Flanged PN 16 / PN 25 / ANSI 150 / ANSI 300
• Temperature Range: -20 °C to +60 °C (standard)

• Natural gas city gate stations
• Industrial gas pressure reduction
• Commercial metering and distribution
• Burner and furnace gas supply
• District regulator stations

Q: What is the accuracy class?

A: Typically AC 5 or AC 10 depending on model and pilot.

Q: Does it have internal relief?

A: Available as an option on some configurations.
