Maintenance
The adjusting nut of each regulator is permanently
lubricated before leaving the factory, and the valve
stem is equipped with a spring loaded Teflon packing
gland assembly so that no maintenance should be
required for the life of the regulator.
The valve stem is set and locked at the factory in a
permanent position to give the valve its proper travel.
No adjustment should be made on the valve stem after
the regulator leaves the factory.
The Spence Strainer protects the valve disc and
seat of the regulator from the destructive effects of
scale, etc. The strainer should be blown out at regular
intervals by removing the plug. For quick blowouts, a
hand valve may be installed on the strainer in place of
the plug.
