Maintenance
General
The only regular maintenance that the Willamette VMC-2200 cone valve requires is to be lubricated
once after the first 50 cycles and then on a yearly basis afterwards. See the lubrication section for
instructions. Whenever the valve is being lubricated, visually inspect the valve for any leakage. If there
is any leakage, see the troubleshooting section at the end of this manual.
Perform any periodic maintenance on the cylinder and hydraulic system as called for in their respective
instruction manual.
Seating in the close position is externally adjustable. However, the seating should not be adjusted until
long term component wear or component replacement requires it.
Lubrication
Lubrication of the valve should be done once after the first 50 cycles of operation. Afterwards, the
valve should be lubricated on a yearly basis. Lubricate at the supplied lubrication points on the valve
assembly and torque unit using a hand-pump grease gun.
Caution!
Do not use air-operated grease
guns. Use Mobilgrease™ FM 222, manufactured by Mobil.
Valve Assembly (18” & Larger)
For valve sizes 18” & larger, the valve body and cover is fitted with two lubrication points for the lower
and upper body bushings. Lubricate at the “Upper Bushing Grease Point” on the cover and the “Lower
Bushing Grease Point” located on the body as shown Figure 1.
The lower bushing grease point may not be easily accessible in vertical valve shaft applications
depending on the installation. If required, the grease fitting supplied with the valve can replaced with an
extension.
Caution!
If a grease extension is required, ensure pressure is relieved from the pipeline & valve before
replacing the grease fitting.
Torque Unit
Lift Nut (All Torque Units)
Grease at “Lift Nut Grease Point” in Figure 2.
T22-18, T68-50, T140-80, & T390-140 Torque Units
Lubrication of the moving parts on the crosshead, crosshead roller, guide rods, link, and lever is
accomplished by applying grease at the “Crosshead Grease Point” and “Lever Grease Point” in
Figure 2.
T8-9 Torque Unit
The T8-9 size torque unit is lubricated differently than all the other torque units because of its small
size. Lubrication of the crosshead, crosshead roller, guide rods and link moving parts is
accomplished by greasing through the supplied fitting connected to the top of the crosshead. To
access the grease fitting, remove one of the two pipe plugs in the torque unit cover shown in Figure
3 depending on whether the valve is in the closed or open position.
