Webster® Oil Safety Valve, 1/2 in Nominal, FNPT Connection, 2.59 in H x 3.24 in W

Webster oil safety valves are ideal for use in oil supply systems which have from 0 to 60 psi supply line pressures on the inlet side of the valve. Requires a sustained vacuum on the outlet side of the valve for fuel to flow to the burner pump. The OSV series provides automatic shut-off for the oil supply in case the line between the device and the burner is broken. Many state and local codes require such a device and also limits inlet pressure on burner pumps to a maximum of 3 psi. Available in 3/8 and 1/2 NPTF porting.

  • By isolating burner fuel pumps from supply line pressure sources a supply pump or overhead tank, the OSV relieves ores sure strain on fuel pump inlets and seals and prevents tank siphoning and spilling caused by accidental line breaks
  • OSV is mounted close to burner assembly
  • OSV operates as pressure reducer with supply line pressure on the valve inlet side and fuel pump vacuum on the valve outlet side
  • 1/2-14 NPTF port size
