Meet the Elektrogas VFH95 DN150 Butterfly Valve — built for the tough jobs where heated air and flue gas need accurate regulation.

Why this valve stands out:

✅ Cast-iron body — rugged enough for demanding industrial environments

✅ Double-eccentricity disc + spring-loaded design — minimizes backlash, delivers high-precision adjustment, and prevents valve floating

✅ Low leakage even when fully closed — thanks to the integrated disc stop

✅ Wide temperature range — handles media up to +250°C (or +450°C with optional dissipators)

✅ Multiple operation options — manual lever, servomotor (modulating/staged control), or solenoid actuator (two-stage control)

✅ Fl**ge installation — fits between two flanges according to EN 1092 PN16

Where it works best:

🔧 Industrial burner systems
🔧 Boiler plants
🔧 Combustion processes with heated air or flue gas
🔧 Any application requiring reliable gas/air flow regulation in high-temperature environments

Need a different size? Check out these other VFH series models:

🔹 VFH4 DN40 — compact solution for smaller setups
🔹 VFH6 DN50 — the go-to mid-range option
🔹 VFH8 DN80 — balanced performance for standard applications
🔹 VFH9 DN100 — stepped-up capacity when you need more flow

All share the same cast-iron durability and precision engineering — just different sizes to match your system requirements.
