Kromschroder Gas Pressure Regulator VGBF 40R40-3Z

The Kromschroder VGBF 40R40-3Z Gas Pressure Regulator

is a high-performance industrial regulator designed to maintain constant outlet gas pressure in combustion and gas distribution systems. It belongs to the VGBF series, widely used in burner management and industrial heating applications.

This regulator features a spring-loaded mechanism combined with an inlet pressure compensation diaphragm, ensuring precise pressure control even when inlet pressure and gas flow fluctuate. It also includes a zero shut-off function, which prevents gas leakage when the system is idle, enhancing operational safety.

The DN40 (1½") threaded connection (Rp) makes it suitable for medium-capacity gas pipelines, while the regulator supports a maximum inlet pressure of up to 4 bar.

Additional features such as test points (screw plugs) at inlet and outlet allow easy pressure monitoring and maintenance. The regulator is built for use with gaseous fuels such as natural gas, LPG, and industrial fuel gases, ensuring stable and efficient combustion performance.

The VGBF series is widely used in industries like steel, glass, ceramics, and commercial heating systems where maintaining consistent gas pressure is critical for safety and efficiency.
