crown engineering OSVA50BIO Webster Oil Safety Valve 1/2 Biofuel

The crown engineering OSVA50BIO Webster Oil Safety Valve regulates stopping oil from flowing when unsafe pressure or flow conditions are detected in the fuel delivery lines. It works through a built-in safety mechanism that reacts to changes in oil pressure, which acts to safeguard the burners, and other parts of HVAC systems like oil-fired boilers and heating systems. Installed on the fuel line with a 1/2" connection, it is compatible with biofuel systems for correct flow control. It is used to prevent fuel leakage, assist in safe burner operation and control fuel supply to the heating equipment.
