Standard Purging Type
Suitable for most applications, this type is furnished as standard. Packing can be replaced without removal of the operator in most cases. Lantern Gland and a pipe connection can provide purging of deposits around valve shaft. Recommended for valves handling fluids with entrained solids and where fluids condense or solidify with loss
of temperature.
Dirty Service Lubricating Type
Similar to standard stuffing box but an addition of a wiper ring of packing before the
inboard bushing to prevent contaminates from galling up surfaces between the bushing and the shaft.
When service requires additional lubricant, a lantern gland and a pipe connection can be furnished. Additional packing rings below gland prevent lubricant from entering the stream.
