Pressure-Reducing and Ratio Regulators

A Regulator for Every Application

No matter your application, Kromschröder has a regulator to fit your need. Whether you're after a pressure-reducing regulator for your main fuel train, ratio regulators for your burner trains, or overpressure shut-offs to safeguard your pressure-sensitive equipment downstream, you'll find it all here. With a variety of sizes, springs, and spare parts, it's just as easy to keep your old Kromschröder regulator running as it is to spec a brand new one.

GDJ and VGBF pressure-reducing regulators are spring-loaded with pressure compensation diaphragms and zero shut-off to maintain the set outlet pressure despite changing gas flow rates. GDJs are the perfect solution for applications where gas or air pressures do not exceed 5psig, while VGBFs are best for high-pressure gas applications –  available for pressures up to 60psig.

GIK, GIK..B, and GIKH ratio regulators are just what you need to maintain a constant gas/air ratio supplied to your burners. GIKs maintain a ratio of 1:1 for continuous control, while GIKHs maintain a ratio of 4:1 on systems using preheated air. GIK..Bs maintain a 1:1 gas/air ratio for intermittent control – making them the preferred choice for pulse-fire applications!

JSAV overpressure shut-off valves, used in conjunction with VSBV safety relief valves are your best bet for securing downstream fittings against excess gas pressure.

Versions of these regulators are available as an integrated part of the Valvario safety shut-off valve product line. For more information, visit our Valvario product pages or contact Combustion 911.

Gas/Air Ratio Regulators

Gas/Air Ratio Regulator GIK

Gas/Air Ratio Regulator GIK

GIK regulators hold constant gas/air ratios on nozzle mix and premix burner systems. They are designed and built with precise internal tolerances, and they provide highly accurate, repeatable pressure tracking over the turndown range of the burner system.

Variable Gas/Air Ratio Regulator GIKH

Variable Gas/Air Ratio Regulator GIKH

GIKH regulators allow precise, repeatable control of gas/air ratios on preheated air combustion systems where air density is affected by temperature changes.

Gas Pressure Regulators

Gas Pressure Regulator GDJ

Gas Pressure Regulator GDJ

GDJ regulators are general-purpose regulators for controlling gas pressure to furnace ovens and other gas-consuming appliances. They are suitable for natural, LP, and clean dry bio-gas at inlet pressures up to 5 psig (350 mbar).

Gas Pressure Regulator VGBF

Gas Pressure Regulator VGBF

VGBF regulators are general-purpose regulators for controlling gas pressure to furnaces, ovens, and other gas consuming equipment. They are suitable for natural, LP, and clean biogas at inlet pressures up to 60 psig (4 bar).

Gas Pressure Regulator with Overpressure Shut-off Valve JSAV
