This Velocity Boiler Works component is a Gas Control Venturi, an essential part of a boiler system. It is designed to regulate the mixture of gas and air that is fed into the combustion chamber of the boiler. The venturi effect, which this component utilizes, allows for a precise control over the gas-air mixture by creating a pressure differential. This ensures optimal combustion efficiency and reduces wastage of fuel. Made from high-quality materials, it offers durability and reliability in various operating conditions. The product adheres to industry standards for safety and performance.
