Honeywell 45900450P-010, venturi di medie dimensioni con valvola a farfalla

Honeywell Venturi tube 45900450P-010B (medium size) — a high-quality component for gas-air mixing systems in modern condensing boilers and industrial premix burners. Advantages and key features: Efficient gas and air mixing — creates a stable gas:air ratio (1:1), ensuring complete and economical fuel combustion. Wide modulation range — smooth burner power regulation from 100% to 20% of maximum load (approximately 85–165 kW depending on configuration) without loss of efficiency. Robust construction — made of durable aluminum alloy (Zamak/ZnAl), resistant to gas environments. Includes necessary seals (O-ring, NBR) for airtight installation. Compatibility — works perfectly with Honeywell gas valves VR46..V(B)/VR86..V(B), VR4..V/VR8..V and fans type G1G144, RG148 and similar. Suitable for assembling condensing boilers with Giannoni TRIO and DUO heat exchangers (TRIO 200, DUO 100, etc.). Why choose this Honeywell Venturi tube? Honeywell Venturi tube 45900450P-010B is a professional solution for creating highly efficient heating systems. Thanks to the Venturi principle, negative pressure is created in the body, which precisely meters gas flow depending on air flow. This guarantees: Minimum gas consumption and reduced operating costs. Low level of harmful emissions (CO₂ and CO). Stable operation even with deep modulation. Easy installation in various positions (horizontal, vertical, up to 6–9 positions on the fan). Application: industrial and domestic heating boilers, condensing systems, premix gas-air generators. Materials: high-quality
