The Tartarini FL Series is a pilot-operated, pressure-balanced pressure reducing regulator designed for demanding natural gas applications. Built with axial flow design, it delivers accurate pressure control, smooth operation, and tight shutoff in high-capacity systems. Its robust construction ensures long service life with minimal maintenance, making it a trusted choice for critical gas infrastructure.
| Parameter | Details |
|---|---|
| Available Configurations | FL (Regulator or Monitor); FL-BP; MFL & MFL-BP (Regulator + Monitor); BFL & BFL-BP (Regulator + Shutoff). Optional silencers (SR/SRII/SRS). |
| Body Sizes | DN 25 to 250 / NPS 1 to 10 (some restrictions by configuration). |
| End Connections | PN 16/25, CL150, CL300, CL600 RF flanges. |
| Inlet Pressure Range | Up to 1480 psig / 100 bar (varies by flange rating: 0.2–100 bar typical). |
| Outlet Pressure Range | 0.01–80 bar / 0.15–1160 psig (depending on pilot and region). |
| Minimum Operating Differential | 0.2–0.5 bar / 2.9–7.3 psig (start open); higher for full open. |
| Temperature Capabilities | Standard: -10°C to 60°C; Low temp: -20°C to 60°C. |
| Accuracy & Shutoff | High accuracy; bubble-tight shutoff with soft seat and knife-edge plug. |
| Materials | Durable steel body, Nitrile/FKM seals, compatible with natural gas and similar non-corrosive gases. |
Ideal for high-pressure natural gas transmission, city gate stations, large-capacity distribution networks, power plant fuel gas feeds, and industrial gas systems requiring precise downstream pressure control.
Users often face issues like noise in high-flow setups, pressure instability during demand fluctuations, or wear in harsh conditions. The FL Series addresses these with optional silencers, fast pilot response, and robust balanced design for quieter, more stable performance.
Direct or compatible replacements for older Tartarini or similar pilot-operated regulators in FL-equivalent sizes and pressure classes from other brands in gas regulation service.
