Stem Tube Covers

What can be said about valve stem tube covers? infact a lot. These rising indicator stem tube covers are for a local refinery for use in a tank farm. The rising indicator is weighted meaning that the top of the stem does not require threading to attach the indicator rod. The stem rod and cover is stainless steel, the rod is fully sealed to exclude water etc, in addition we have a specially designed adaptor which channels any moisture which is generally due to condensation, to the external of the stem tube cover, this ensures no build up of water which results in corrosion of valve components and some instances the thrust assembly of the actuator. Indicators will be fitted to Limitorque MX, Exd actuators. gatevalve actuators valves acrodyne actuator
