WEBSTER 1/2" OIL SAFTEY VALVE OSVA50 OSV SERIES  OIL SAFETY VALVES  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. 1/2 NPTF porting. UL listed.  Webster OSV® valves can be used for the following applications which require slightly different installations: 1. Preventing tank siphoning and oil leaks in the event of line  breaks.  2. For use with a supply pump (booster pump) to prevent  excessive pressure at the inlet of the burner fuel unit.
