REGULATORS

	Balanced Zero-Ratio Regulators (BZR) BZR Regulators are normally closed, balanced to near zero or atmospheric pressure with factory calibrated and sealed tension springs for accurate flow ratio control. Units can be referenced to atmosphere, to controlled combustion air supply or to the combustion chamber. The BZR regulators, provided they are matched appropriately with the mixing system, will provide the correct fuel/air ratio over the complete turndown range of the burner system.

	Balanced Zero-Ratio Regulators (BZR) 300oF These regulators have the same capability as the standard BZR series except that they are designed to operate with suitable fuels up to 150 oC (300oF). Click On Image to Download Detailed PDF File
	Balanced Zero-Ratio Regulators (BZR) 500oF These regulators have the same capability as the standard BZR series except that they are designed to operate with suitable fuels up to 260 oC (500oF). Click On Image to Download Detailed PDF File
	Balanced Zero-Ratio Regulators (BZR) 700oF These regulators have the same capability as the standard BZR series except that they are designed to operate with high temperature vapourised fuels, such as kerosene and naptha, up to 370 oC (700oF). Click On Image to Download Detailed PDF File
	Spring Biased Ratio Regulators (BZR-B) These regulators are designed for use on systems using excess air. The BZR-B unit can maintain the fuel/air ratio at stoichiometric conditions at high fire and create a lean burner condition when the system goes to low fire and excess air operation.
