Kromschroder Gas pressure regulator VGBF50F10-3 86048210

The Kromschroder VGBF50F10-3 gas pressure regulator (SKU 86048210) is a spring-loaded, flanged reducer with a nominal diameter of DN 50. It maintains a constant outlet pressure within a range of 0.1–0.3 mbar, with a factory setting of 20 mbar, and is designed for a maximum inlet pressure of 0.01 mbar. This regulator features inlet pressure compensation, a built-in safety diaphragm with zero shut-off, and is suitable for natural gas, LPG, and air. It operates in ambient temperatures from -15 °C and complies with EN 88, EN 334, and CE standards.

When selecting a replacement gas pressure regulator of this type, ensure the connection type (flanged) and nominal diameter match the existing pipeline. Verify the maximum inlet pressure and outlet pressure range are compatible with your system's requirements. The regulator must be installed in the correct orientation as specified by the manufacturer to ensure proper diaphragm movement and pressure stability.

Common failure modes for this kind of regulator include a torn diaphragm, weakened spring, or clogged filter, leading to outlet pressure drift. Symptoms may include low or unstable burner output, but the gas flow will not be completely shut off if the regulator fails. Check the diaphragm, spring, and filter screen for damage or blockage when pressure instability is observed.
