Check Valves lend themselves to easy upgrade. By replacing disc, tail link, shaft bearing, stuffing box assemblies along with rockshaft and gaskets, valves can be brought back to near new condition. Air actuators require only a seal kit with a spring.
When ordering refurbishment services be sure to give all the data on the valve reference plate, the number of the sectional illustration, and piece list forming part of this bulletin. Also, the name and number of the parts required as numbered and described.
