Auburn Ignitors OSVA38BIO Webster OSV 3/8" Oil Safety Valve Biofuel Compatible

The Auburn Ignitors OSVA38BIO is a Webster OSV 3/8 inch oil safety valve designed for HVAC systems with stainless steel inlet and outlet construction. This oil-protective valve automatically closes the oil supply if there is a line rupture, preventing oil spills and safety hazards.

Key Features:

• Compatible with biofuels (B20-B100), #1-#2 fuel oil, kerosene, diesel, and waste oil
• Ideal for oil supply systems with 0 to 60 PSI supply line pressures on the inlet side, providing automatic shut-off if the line between the device and burner is broken
• Vacuum-operated design opens when sustained vacuum is generated by fuel unit operation at the outlet side
• Works safely at pressures up to 60 PSI and meets UL requirements while improving system stability for vacuum-based fuel supply
• Available with 3/8 inch NPTF porting and UL listed for safety compliance

Many state and local codes require such a safety device and also limit inlet pressure on burner pumps to a maximum of 3 PSI. This valve is installed close to the burner assembly in the suction line between the oil tank and the heating unit, providing essential protection for residential and commercial oil heating systems.
