Unlike isolation valves, control valves have a significantly higher number of operating cycles per day. These valves continuously throttle to maintain process variables, e.g. pressure, temperature and flow rate. Due to frequent movement of the stem inside the packing box, control valve seals wear at a much quicker pace. This means, the steam-seal packing box interface is at higher risk of leakage as compared to previously mentioned static gasket joints and should be monitored and maintained whenever possible.
