- Application
The Model V Back Pressure Regulating Valve is a self operated, spring-loaded back pressure regulating valve. Typically the Model V is installed at the far end of the oil supply line, down stream of the boiler fuel metering valves and passes unburned oil to the return line. Alternately, the Model V may be installed upstream of the boiler fuel metering valves. In both cases the valve passes oil to the return line in order to maintain a constant supply pressure to the fuel metering valves.

The Model V is a 1" NPT, 250 lb. cast iron body, balanced cage, hardened and polished stainless steel trim. The 30 to 150 PSI range valve has a Teflon seat and stainless steel diaphragm while other ranges have Viton seats and six (6) ply Teflon composition diaphragms for increased responsiveness. The valve capacities are shown in the table below.
