Webster Fuel Pumps & Valve Oil Safety Oil

Webster oil safety valves (OSV) protect oil burner supply systems that run on #2 fuel oil. They are used in oil-fired heating systems with pressurized supply lines. Each valve is a vacuum-operated safety device, also called an oil line safety valve or fuel oil safety valve. It helps prevent fuel spills caused by accidental line breaks.

Key Features:

• Relieves pressure strain on burner fuel pump inlets and seals
• Prevents tank siphoning and oil spills if a supply line breaks or a fitting leaks
• Works automatically. The valve opens only when the burner fuel pump creates vacuum on the outlet side, and it stays closed when the burner is off
• Mounts close to the burner assembly. Supply line pressure is on the inlet side and fuel pump vacuum is on the outlet side
• Female threaded connections at both ends
• UL standard, for use in oil supply systems

These valves add a layer of safety and help protect equipment in residential and commercial oil heating installations.
