Crown Engineering OSVA50 Valve
The Crown Engineering OSVA50 is a heavy-duty Webster Oil Safety Valve (OSV) designed for professional oil-fired heating system installations. This 1/2" NPT oil safety valve acts as a critical pressure-reducing diaphragm, preventing line pressure from reaching the burner pump when the unit is not in operation. By maintaining a vacuum on the supply side, the Crown Engineering OSVA50 effectively eliminates the risk of environmental oil leaks caused by line ruptures or loose fittings below the tank fuel level. It is rated for fuel oil systems utilizing No. 1 or No. 2 fuel oil and is an essential component for meeting local fire codes that mandate protection against siphonage or tank failures. This HVAC oil safety valve is built to withstand the rigors of boiler room environments, providing consistent fail-safe performance and assisting in the stabilization of pump inlet pressure during high-demand cycles.
Key Benefits for HVACR Contractors:
- System Safety: Automatically shuts off oil flow in the event of a line break between the valve and the burner.
- Vacuum Operation: Engineered to open only when the burner pump creates a vacuum, preventing gravity-fed leaks.
- 1/2" NPT Connections: Standard sizing for seamless integration into existing residential and commercial heating oil supply lines.
- Durable Construction: Manufactured by Crown Engineering to precise tolerances for industrial-grade reliability in oil-fired applications.
- Regulatory Compliance: Assists technicians in meeting safety standards for overhead tanks or systems with high static pressure heads.
Common Questions:
How does the OSVA50 prevent oil spills?
The valve remains closed until the fuel pump generates a suction vacuum. If a line rupture occurs, the vacuum is lost, and the internal diaphragm instantly seals, stopping the flow of oil from the tank.
Is this valve compatible with bio-fuel blends?
This Crown Engineering OSVA50 technical specification is primarily validated for standard No. 1 and No. 2 fuel oils. Always verify specific bio-blend percentages against the diaphragm elastomer compatibility before installation.
At what pressure should this Webster OSV be installed?
It is typically installed on the supply line where the tank is located at a higher elevation than the burner, or in any pressurized supply system where anti-siphon protection is required.
Safety Information:
This product carries a California Proposition 65 warning, as it may contain chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
